Christopher-
By the way, if the devs want help with documentation of the code, I can do some.
Well, it would help to have a decent user documentation as well. The help is being maintained at Meta, but there's really not enough people there who work on it: http://meta.wikimedia.org/wiki/Help:Contents
This is something everyone with some understanding of how the wiki works can help with. It is essential for new projects like Wikinews, which rely on these pages, as well as for other users of MediaWiki outside the Foundation framework.
Much of what currently is there is out of date or inaccurate. It also doesn't follow consistent guidelines for interwiki linking, images etc., which is key to portability. So any participation would be greatly appreciated.
If there are any questions, there's usually someone on #mediawiki (irc.freenode.net) who can help.
Regards,
Erik
