Not to say that they shouldn't put one on this site, but as an option, since I'm not sure how much bandwidth they're allowed, and since we overloaded the old server on a number of occasions last year, might I suggest just putting an interface to the Tigerbolt chat? The Java interface for it is awesome, and for those of you who just really don't like Java, there's always direct IRC access using mIRC or something similar:
Server: irc.webmaster.com
Channel: #firstrobotics
Page Link:
http://www.rit.edu/~us1stwww/chatindex.html
(I think that's the right link, it's been a while since I've used it)
