1. channel [IRC] The basic unit of discussion on IRC.
Once one joins a channel, everything one types is read by others on that
channel. Channels are named with strings that begin with a ‘#’
sign and can havetopic descriptions (which are generally irrelevant to the
actual subject of discussion). Some notablechannels are #initgame, #hottub,
callahans, and #report. At times of international crisis, #report has hundreds of members, some of whom take
turns listening to various newsservices and typing in summaries of the
news, or in some cases, giving first-hand accounts of the action (e.g.,
Scudmissile attacks in Tel Aviv during the Gulf War in 1991).
