Athena has a legacy networked conferencing system called Discuss that is used by many people in the community to, well, discuss things. This system is also used to archive many of the email lists used by the MIT community, so you will likely find yourself needing to have a look at the system. Several Discuss clients exist, including the shell client discuss and the graphical client xdsc, and the http://www.diswww.mit.edu archives can also be seen from a Web gateway. For more information on Discuss, there is the SIPB-maintained document http://www.mit.edu/afs/sipb/project/www/discuss/discuss.htmlUsing Discuss.
