newsgroup

newsgroup n.  [Usenet] One of {Usenet}'s huge collection of
   topic groups or {fora}.  Usenet groups can be `unmoderated'
   (anyone can post) or `moderated' (submissions are automatically
   directed to a moderator, who edits or filters and then posts the
   results).  Some newsgroups have parallel {mailing list}s for
   Internet people with no netnews access, with postings to the group
   automatically propagated to the list and vice versa.  Some
   moderated groups (especially those which are actually gatewayed
   Internet mailing lists) are distributed as `digests', with groups
   of postings periodically collected into a single large posting with
   an index.

   Among the best-known are comp.lang.c (the C-language forum),
   comp.arch (on computer architectures), comp.unix.wizards
   (for UNIX wizards), rec.arts.sf.written and siblings (for
   science-fiction fans), and talk.politics.misc (miscellaneous
   political discussions and {flamage}).
