>> How do I delete a previous message that I don't want up anymore? <<
The sysops discourage message deletion because it disrupts the thread
continuity.
However, as the author of a message or recipient of one, you DO have the
ability to do so. Your CIS software may or may not allow this, so you would
likely have to log in and run in an interactive mode. I believe the command is
"DEL" at the message prompt, and you must then provide the message number you
wish to delete. Again, this is really discouraged because of the disruption to
the forum threads. If your message contains personal information such as
phone numbers, addresses, etc. bring it to the attention of the sysop and it
can be removed for you.
