Looking for a low volume, probably no more that 20-30 users, Open Source message/bulletin board.  Obviously must be written in something which our web server supports, PHP/Python/Ruby etc.  Any suggestions?
Thanks,
  Nick
PhpBB is an excellent. It's very easy to set up and has many great features, but it is more difficult to customize right out of the box. For a superfast "community" solution, try using WordPress with the BuddyPress plugin.
