                        Online Guided Tour of CLU-IN
I. Introduction
Welcome to your guided tour of the Cleanup Information Bulletin Board System (CLU-IN
BBS). The purpose of the tour is to make your first session online a successful one, even if
you have no previous experience on other bulletin board systems (BBSs). If you are new to
the BBS environment, I strongly suggest that you use this guided tour for your first online
session. The guided tour will walk  you through using each of the main features of CLU-IN so
you'll understand what it can and can't do. As part of this tour, you will learn how to:

•  Log onto the system
•  Read messages
•  Send  messages
•  Use the online help
•  Read bulletins
•  Download a file
•  Upload a file
•  Join a special interest group (SIG)
•  Exit the system

The tour  should take from 30 minutes to an hour. If you don't have time to complete all the
activities outlined in one session, you can complete your tour over the course of a couple of
sessions.  Each section of the guided tour starts at the "Main Board Command?" prompt, so
you can easily jump into the guided tour at the start of any section.

Each time you call CLU-IN, you are limited to one hour of online time. If you should ever
run out of time (BBS Warning: CAUTION: Auto-Disconnect in (2) min.!), you may call
back immediately and start another session.  The purpose of the limit is to give other callers a
chance to call into the BBS.

If you  are familiar with other BBSs, you may just want to read through the pre-tour
preparation sections quickly to familiarize yourself with the features that are unique to CLU-
IN.
II. Pre-Tour Preparation—Telecommunications Software	

ATTENTION: DO THE PRE-TOUR PREPARATION BEFORE YOU SIGN ON. IF YOU DON'T, YOU WILL NOT BE ABLE TO
DO ALL THE ACTIVITIES IN THE TOURI

To have the most enjoyable and profitable time during your guided tour, it is important to do
a few things in preparation. If you follow the instructions in the next few paragraphs, you will
be able to participate fully  in all the later guided tour activities.

-------
   Be Able to Sign On

The guided tour starts as you sign on to CLU-IN and enter your name. If you are having
trouble getting to this point, please refer to the information in Chapter 3 of the CLU-IN Users
Guide, your modem manual, or your communications software manual.

You should do the pre-tour preparation before you attempt to sign on, so you will be ready to
do the tour the first  time you connect.

   Learn Some Key Facts About Your Communications Software

Before starting on the tour, you should take a few moments to familiarize yourself with the
features  of your communications software that you will need to know to perform all the
functions in the tour. CrossTalk and ProComm are two common communications software
programs. The communications software program acts as the coordinator between your
computer, your modem, and the BBS computer. Use the communications software user's
manual or help screens to learn how to use the following functions: file transfer protocol,
terminal emulation,  and printing BBS screens or capturing them to a file on your computer.

   (D File Transfer Protocol

First, you should consult your communications software manual and determine which file
transfer  protocols  it  supports. The transfer protocol is a setting needed to exchange files with
a BBS—something you will be doing during this guided tour. The transfer protocol is a
common "language" that computers use when they exchange files (uploading/downloading).
Some common protocols are XModem, YModem, ZModem, and Kermit. You will need to
know which protocols your software supports so you can choose the appropriate protocol on
CLU-IN when uploading or downloading.

   @ Terminal Emulation

Terminal emulation  is a setting in your communications software that controls how certain
keystrokes and graphics features will work while you are connected to the BBS. In order to
use the graphics mode of the BBS or the full-screen message editor, your communications
software must be  able to emulate a VT-100 terminal. Most commercial communications
software has a setting for terminal emulation that will allow you to select VT-100 (or ANSI)
emulation. Check your communications software manual to see how to change the emulation
setting,  if necessary. If your software does not support VT-100 emulation, you can still use
the BBS, but you will not be able to use graphics mode or the full-screen message editor.
Graphics mode consists of color screens and fancier graphics, but the content of the screens is
the same whether or not in graphics mode. The full-screen editor provides more sophisticated
entry and editing  of messages, but you can still enter messages without the full-screen editor.
The difference is  that without the full-screen editor, you enter and edit a message one line at
a time and the editing capabilities are less flexible.

-------
   (D  Printing or Saving Online Information

Your communications software will allow you to save a record of your online visit to the
BBS, including messages to and from you, results of database searches, and the text of
bulletins.

To print the information that scrolls across your screen while you are on the BBS, you must
use your communications software print feature. You can use this feature at any time during
your online session. Make sure your printer is turned on and ready to accept characters. Then
turn the printer feature ON from the communications software menu/command line. From this
point on, everything that scrolls across the screen on the BBS  will print out on your printer.
When you no longer want to print the information scrolling by, turn the print feature OFF.
You will still be connected to the BBS.

To make a computer file out of the information that scrolls across your screen on the BBS,
you must use your communications software log file or capture feature.

You can use this feature at any time during your online session. Turn the log file/capture
feature ON from the communications  software  menu/command line.

Depending on the communications software package you use, you may be prompted for a
path and file name. At this prompt, you  can type in a path and file name to direct this
information to be  saved in any directory on your hard drive or on a floppy disk. If you do not
select a path and file name,  the information will be saved to the default path and file name
already set up in your communications software settings.

From this point on, everything that scrolls across the screen on the BBS will be  saved in  an
ASCII-format file. When you no longer  want to save the information scrolling by, turn the
log file/capture feature OFF. You will still be connected to the BBS. After you exit the BBS,
you can use any word-processing software package to view, edit, or print the information in
the file you created.

III. Pre-Tour Preparation—Creating a  File and Disk for the Tour	

   Create an ASCII File to  Upload

Since a BBS is an interactive environment, you will get the most out of it if you learn how to
upload (send) or download (receive) materials to the BBS.

A portion of the guided tour will be devoted to uploading a small file to the BBS for practice.
To do this portion of the tour, you will need to create a small ASCII text file for uploading
BEFORE you start the tour.

I recommend that you write a one-line letter to the system operator explaining that you are
practicing uploading. You can write this letter using any word-processing program. The only

-------
trick is that you MUST save it in ASCII or DOS-text format. Any full-feature word processor
will offer the option to save text files in ASCII or DOS-text format.

Please give this test upload file a particular type of name. This will make the file name
unique and help our SYSOP find these test files easily in the system. Make the first part of
the file name the seven digits of your phone number and make the extension of the file  name
"xxx." An example file name: 5521234.xxx.

Remember the name (e.g., 5521234.xxx) and location (e.g., disk drive and subdirectory A:,
C:\WP51\UPLOADS, F:\HOME\UPLOADS\)  of the file on your computer, as you will need
to tell your communications software program exactly where it can find the file and what the
file is called (the path and file name) before the program can send the file to the BBS.

Sample Letter:

   Dear Sysop,
   I am practicing uploading. Please delete this file from the system.

   Thanks!

   Prepare a Disk for Downloading a File

Files of various types are available on CLU-IN for downloading  (transferring from the BBS
to your computer). Most of the available files have been compressed (zipped) using a utility
called PKZIP.  The PKZIP program compresses the file size  to make the transfer faster and
allows the combination of more than one file  into a single compressed file. Zipped files have
the suffix ".zip" as part of their filename. To use a zipped file after you have downloaded it,
you must unzip it to restore it to its original form.

The utility program you will need to unzip downloaded files is available on the BBS. As part
of the guided tour, you will download this utility program to your computer for future use. If
you do not have a hard drive, you should have a blank, formatted floppy disk ready to accept
this program before you start the guided tour.

IV. The  Tour Begins

If you have already registered as  a new user with CLU-IN, skip this section and go on to  the
section entitled, "Reading the News File" on page 7.

You must now use your computer and modem to dial into CLU-IN. If you are not sure  how
to place a call with your computer, check your communications software manual. The dial-in
number for CLU-IN is 301-589-8366. Your communications parameters should be set to 8
data bits, 1 stop bit, and no parity. If your software supports it, you should set your terminal
emulation at VT-100 or ANSI. The speed can be set at 1200, 2400, or 9600 baud.

-------
The first time you connect to CLU-IN, you will be asked to answer some brief questions.
Please answer these questions as completely as possible. Knowing who is using CLU-IN will
help CLU-IN staff better serve the BBS users.


Remember, you must always press the  key to send your commands to the BBS.


Use your modem to dial the BBS. Once you connect to CLU-IN you will see the following
screen:

CARRIER 2400 PROT: NONE CONNECT 2400
CONNECT 2400 / 10-06-92  (21:59:53)

<« CLU-IN: Cleanup Information Bulletin Board >»
PCBoard (R) v!4.5a/E25 - Node 1 - EFEA7EOCFF8C

If you have an IBM-compatible, do you want graphics? (=no)?

This screen indicates the baud rate (or speed) at which you are connected to CLU-IN and
asks whether or not you wish to use graphics mode. If your communications software has
been set to emulate VT-100 or ANSI, then you may type Y for yes. If you cannot use VT-
100 emulation or ANSI, or if you do not know, type N or just hit  as the prompt
"=no" indicates. The graphics mode consists of color and several graphics screens.
The information on CLU-IN is the same regardless of whether or not you use graphics mode.

V. Reading the News File	


If this is your first time online, you will automatically see a display of system news called the
"news file" for the BBS. You will see this screen the first time you log on and thereafter only
when it is updated by the system operator (SYSOP).

If you have been on CLU-IN before and the news file has not been updated since your last
call, it will not be displayed. You can type NEWS at the "Main Board Command?" prompt
to display the news file at any time.


I                                   NEWS                                        |

You are now at the central hub of the BBS—otherwise known as the Main Board. The menu
above tells you all the things you can do.
VII. Reading the Public Messages	

Let's take a look at the public messages posted by other users.

There are many ways to approach reading the messages—reading only new ones, reading
from newest to oldest, reading those on a certain topic, etc. You can refer to Chapter 4 of the
manual for more details.

Right now we are going to read (R) all the messages posted since (S) the last time you were
online. At this time, the "R S" command will show you all the public messages ever posted.
In the future, this command will show you only public messages that you have not yet seen.

-------
At the end of each message, you have the choice of reading the next message or not reading
any further messages.

Please spend as long as you like reading the public messages. To continue with the tour, you
will need to return to the "Main Board Command?" prompt. From the "End of Message
Command?" prompt, you can always press  to continue reading messages or N (to
stop reading messages and return to "Main Board Command?" prompt).
VIII. Posting a Message


Now it's time for you to post a message of your own. This first time, you can send a private
message to the SYSOP. To send private messages to other users, you would address messages
to them by name.

From the "Main Board Command?" prompt, type E

To  (='ALLf) ?  SYSOP

Subject «ENTER>=abort)? TAKING THE TOUR

Message Security (H)=help?  R

Selecting "r" (for receiver only) as the message security ensures that the receiver (in this case,
SYSOP) will be the only person who can read your message. If you wanted to post a public
message like the ones we read previously, you would select "N" (no security).

Use  Full Screen  Editor? Y

The full screen editor allows you to type your letter using a full screen word-processing
program instead of a more primitive line editor. However, you must be using VT-100
emulation in order to use the full screen editor. If you are not using VT-100 emulation, you
must type N instead of Y.

Press  to continue

Your message has  now been saved to the BBS's disk and sent to the SYSOP's mailbox.


IX. Using the Online Help System	

Let's take just a moment to see how the online help system works. Suppose you want to read
all new messages, but aren't sure  exactly how  to do this. First, you would check the menu
that is displayed with the "Main Board Command?" prompt and select the command for
[R]ead messages.

(xx  min left)  Main Board Command? R

(H)elp,  (1-413), Message Read Command?  H

(R)ead  Messages  - Function Help

Subcommands:
        (#)       a  message number between 1 and 9999999
        (F)       selects only messages from you
        (Y)       selects only messages left for you
        (YA)      selects only messages left for you  or addressed to  "ALL"
        (S)       selects messages newer  than the last  one you have read


As you can see, the (S) command allows you to read messages newer than the last you  have
read. When you have finished reading the help screens (either because you read the whole
thing or you typed N for "(N)o more", you will be returned to the "Message Read
Command?" prompt (the same one from which you requested help).

(H)elp,  (1-413), Message Read Command?  

The online help system is available from any prompt on CLU-IN.
User responses to prompts are indicated by Bold type. Remember to press  after every response to send
your input to the BBS.                                                                11

-------
X. Reading Bulletins
Bulletins are short text files that you can read while you are on the BBS.

Now is a good time to practice capturing online text to a file on your computer system. If
you followed instructions in the pre-preparation section of the tour, you now know how to
turn on the log file/capture feature of your communication software.

(Optional: If you want to capture the text from the following practice session,
execute whatever commands are needed to turn on your system's log file/
capture feature now.)

From the "Main Board Command?" prompt, type B.

(H)elp,  (1-14), Bulletin List Command?  5


Bulletin 5 contains useful information on using the file compression/decompression
(zip/unzip) utility program discussed in the pre-preparation section. If your log file/capture is
ON, you will be capturing the text of this bulletin to your computer for later reference.


=======================[CLU-IN  BBS  Bulletin  5]=======================

Most of the files available  in  the  downloading directories are compressed to
conserve room  and reduce transmission time.   In some cases, multiple files
are packed into a single "package"  or archive.   These files all have the
extension ".ZIP," such as  "TREATEXE.ZIP." When you download them, you will
not be able to use them or even  read them until they are unarchived or
"unzipped."  This operation  requires a  program called PKUNZIP.
PKUNZIP is a very fast archive  extractor that is available from
File Directory 1 on this bulletin board.

Give the command "F 1" at  the main  menu prompt to see Directory 1.  You will
see listed a file called PKZ110.EXE. That is a special file containing
PKUNZIP and related files, including the documentation.

In order to use files with an  .ZIP  extension, you first have to download
PKZ110.EXE.  Once you've downloaded it, get  out of CrossTalk and type PKZ110
at the DOS prompt.  Be sure  you  are in  the same subdirectory that holds
PKZ110.EXE when you do this.  It will automatically unpack itself into
different files, telling you it's  "uncrunching" and "unsquashing" as it
goes.  The one file you downloaded  will have unzipped itself into several
files.  Look for a file called  ".DOC" or "README" or "READ.ME" to give
additional instructions.

Now you have PKZIP on your hard disk and you will never have to download it
again.  It stays there and you  will use it every time you want to unzip a
file with a .ZIP suffix.

The next step  is to actually unzip  a file.  First, be sure that the zip'd
file is in the same subdirectory on your hard disk as the files that came
out of PKZ110.EXE.  Then just type  PKUNZIP followed by the name of the
zipped file.   For example, to unzip a file called UPDATE.ZIP, you would
type  (at the DOS prompt) PKUNZIP UPDATE.

If you upload  lengthy files  to  this board, please use PKZIP to create a
compressed file; it will greatly reduce the  size—and transmission time—of
your files.  PKZIP.EXE is  one of the files that came out of PKZIP.EXE when
you unpacked it as described above.  If PKZIP.EXE is in your subdirectory,  and
you want to archive the file "MEETING.LST" that is in floppy drive A: into  an
archive on floppy drive A: called MEETINGS.ZIP, type

                     PKZIP -a A:MEETINGS C:\XTALK\MEETING.LST

This will create the archive on  the "C" drive,  in the "XTALK" subdirectory,
and "add"  (that's what the small "-a" in the command line means) the file to
it. Just remember to put the name  of the archive first and the file or files
that go into it second in  the command line.   Now you'll upload MEETING.ZIP  and
when another user downloads  it,  they will unpack it and have MEETING.LST.
Voila!

User responses to prompts are indicated by Bold type. Remember to press  after every response to send
your input to the BBS.                                                              13

(If you have been capturing the text so far, now execute whatever commands
are needed to turn  off or close your system's log file/capture.)

If you did indeed turn on the file log file/capture, you have the text of Bulletin 5 on Zipping
and Unzipping on your computer's disk for future reference.

Feel free to take a look at other bulletins. When you are finished, return to the "Main Board
Command?" by pressing  from the Bulletin List Command? prompt.
XI. Downloading a File

The files available online are either text files that are too large to be read online as bulletins
or program files to run on your computer after you exit the BBS.

Many of the files available on CLU-IN have been compressed (zipped) to speed the transfer
process between computers. A utility program (referred to in the bulletin that you just read) is
available on  the BBS that will allow you to decompress (unzip) any compressed files you
might acquire from the BBS. You must  transfer (download) it to your computer one time and
then keep it for future use.

As part of the guided tour, we will download this program to your system. You must have
150,000 bytes of room available on your hard drive or a blank floppy disk ready to accept
this file  from the BBS.

First, though, let's take a look at the various types of files that are available.

-------
There is a chance that your upload was not successful the first time. You may want to try the
steps again. If you are unsuccessful a second time, you may want to call the CLU-IN help
line at 301-589-8368 for assistance.

A number of factors can affect the success of an upload. It can be more tricky when you are
accessing the BBS through a mainframe computer, local area network, or shared modem
using a data switch rather than with a PC and modem.
XIII. Joining a Special Interest Group (SIG)	


The SIGs on CLU-IN are special sub-areas of the BBS with all the features of the Main
Board of the BBS, but limited to a particular topic or audience. When you enter (join) one of
these SIGs, you will notice that all the messages, files, and bulletins available are focused on
the SIG topic. To see a list of available SIGs, type J.

XV. Shortcuts for Your Next Online Session

You might have quickly skimmed over the messages, bulletins, and files available online
during the guided tour. If so, you may wish to look at these features in more detail next time.
To do this, simply use the commands given in the guided tour again. These commands give
you the broadest access to the materials online.

In the future, you may wish to review only materials  that are new since your last online
session. Here are some tips on how to do that.

    New Messages

When you first access the BBS, you will be asked whether you want the BBS to review the
message base. If you press  (for yes), the numbers of the  messages you have not
yet read will be displayed.
 User responses to prompts are indicated by Bold type. Remember to press  after every response to send
 your input to the BBS.                                                               22

-------
At the "Main Board Command?" prompt, type RY and press  to see all
your messages, or type RS to see all the new messages posted since the last
message you read (including private messages addressed to you and all new public messages).

    New Bulletins

The numbers of all the bulletins that have been updated since your last BBS session
(including, unfortunately, the ones that have recently been deleted) will be displayed as you
enter the BBS. To read any new bulletins, at the "Main Board Command?" prompt, type
BN and press .

    New Files

When viewing a list of files, those that are new since your last BBS session are marked with
a blinking "*". To see a list of recently added files, at the "Main Board Command?" prompt,
type FN and press .  You will be prompted to enter a date from which to
start scanning (the default is about 2 weeks). Select A to view all. This will display a list of
all files that are newer than that date.
