@fxstein: Too bad I didn't see this post earlier... I'm in....
If I can find my way to the latest release, I'll kick in on writing documentation.

Lord knows I've got quite a bit of experience with FB (even having been involved in much of the Numinu template re-write) so I could probably contribute quite a bit, especially when it comes to customizing FB.
I'm currently working on a fairly large project that takes up a lot of my *day*, but I'll contribute as much as I can in the evenings and on weekends...
(Edit: I'm in on helping the docs on FB 2 as well, if you need me...)
