I do cleanup, patrol recent changes, and add to guides for games I play. At the moment, I'm also learning how the MediaWiki software works. So far, I know how to edit LocalSettings.php and install extensions without crashing a wiki (hopefully, I've never done any yet). I'm happy to help with anything, so just ask if you need anything!
