If I could staff for anyone and knew wikidot, I would offer. Wikidot is somewhat different in some pretty important ways from mediawiki, from what I gather.
If you need some help with css, and have someone who decides to fill that role with basic knowledge for wikidot requirements, do feel free to poke me in PM at any time (and they're welcome to do the same) if there's anything I can be of help with.
I have a wiki that's not finished, for a game I set aside in favor of a different idea, that does have some useful templates and code on it here: http://sevendevils.info/index.php/Main_Page
Not all the things I wanted to do with it got done before I set it aside, but if there is something there that looks useful to you that you'd like to implement for your game, I'm happy to talk to whoever your wikidot-savvy staffperson is to try to figure out if it can be done for wikidot and ideally can get it done. I just ask that if there are templates/a nice setup/etc. that comes from it, please be willing to 'pass it on' and share the code with others as well. 🙂
