Any Media Wiki Hackers Available?

I've got a few ideas I'd like to add to comixpedia.org but mediawiki is a tough piece of code to crack from scratch. If anyone is an expert at (1) skins; and/or (2) extensions (I'd like to include files from the other comixpedia sites at comixpedia.org) I'd like to talk to you. Please email me at xerexes AT comixpedia DOT com. Thanks!
