There are lots of things that can be done. If you want to learn building packages, that's fun. :)
The things that slow down the release are a number of mundane things, like writing announcements, using `s/30003/50000/` on the website, etc. ;) The website could certainly use some help. The features page, for example, is quite dated...
If you have a good server on a solid connection, perhaps you could host the forums. I'm sick of updating phpBB all the time and it could use some customization. Same for mediawiki & bugzilla...
Speaking of which, take a look at bugzilla ( http://bugzilla.blagblagblag.org/
), and see if there's anything there you can do.
And writing in the wiki... Lots could be done there.
Anyway, that's a few things that come to mind. :)
