This is a perl CGI script for a blackboard. In fact, the number of blackboards is unlimited and the layout is fully configurable for each blackboard. The blackboard won't accept any HTML codes for input (this is because some people put links to pictures in their texts and when the other computer is off-line at the time that someone wants to see your blackboard it takes a long time before a time out is given, if given at all). To install it do the following things: 1. Copy bb.pl to a subdir (eg blackboard) in your cgi-bin directory. Make it executable with "chmod 755 bb.pl" (or something alike). 2. In this subdir you need 1 other dir (the name is free, you define it in blackboard.cnf (step 3): cgi-bin/blackboard/messages (chmod 777 messages, everyone must read and write to it). 3. Copy blackboard.cnf (this name is coded in the perl script) to cgi-bin/blackboard (next to bb.pl). 4. Edit this file with a text editor for your needs. Example entries are available. Here you define a blackboard entry (between []'s) as called in your header file (step 5) by
