I do cleanup, patrol recent changes, and add to guides for games I play. I can install MediaWiki and extensions of it, and edit most of the LocalSettings.php file (though for really technical things, like actually writing scripts, I'm not the man to ask). Hopefully soon, I'm going to start learning the PHP programming language. I'm happy to help with anything, so just ask if you need anything!
