Sure you can join the dev team, we really need some active people (even just to get something committed). Communication isn't really well organised (or, at all organised). There's a Campfire room that no-one uses, same for an IRC channel and posts on the forum still only come in bursts every so often.

If you want to be able to commit code to the project's subversion repository, I'll just need a gmail (or google accounts) address.
