[Pdx-pm] Bulletin/message board recommendations?

[James marks]

Hi all,

I'm interested in setting up a bulletin/message board on my server as a 
forum for some of my coworkers who are scattered among several 
different locations around Portland.

Any recommendations as to a good bulletin/message board?

I'm looking at yaBB but I'm not really familiar with what else is out 
there (nor am I familiar with yaBB, for that matter). It doesn't 
necessarily have to be a Perl-based system, although it might help me 
learn a little more about Perl if it is.

Thanks!

James
