I have to say, I was not expecting the kind of response we got to Chris's request for help. Thank you all for your enthusiasm and offers of help :)

We've attempted to respond to each email and IM we've received, but if we missed seeing your offer, here's some information to help people get started contributing code.

Getting the code
Check out http://trac.adiumx.com/wiki/GettingAdiumSource for our documentation on getting the code and making sure your coding environment is set up and up to date

Finding things to work on
http://trac.adiumx.com/roadmap is a great place to start looking, but possibly even better is to look into issues that you've run into yourself; personal motivation is always a great way to stay interested.

Asking questions
I've put up a page on the wiki at http://trac.adiumx.com/wiki/DevelopmentTipsAndTricks with some tips and tricks (most of them useful to other cocoa coding as well, actually), and many of the developers hang out on irc and can answer questions. Colin and I (at least, possibly others) are willing to answer questions on IM as well.
