I just found out about the project a couple weeks ago, and was thinking about doing a little something, but the developer page is sorely lacking in this regard (well, beyond the basics anyway). I'm glad this post was brought up - I guess I would have found it in a search, but still!
Actually, the thing I was interested most in working on is the launcher (boring I know, but it could use some work, especially in the beginner usability aspect), but I didn't see the source when I got everything from CVS - though I guess I didn't search for more than a few minutes.
I'll update my resume and forward it on. Probably won't have too much time this summer, but I'm sure I can work on it here and there, and in fall/winter my workload usually drops off a bit.
