Forum:How do I change the default skin for anonymous users?

How do I change the default wiki skin/look for non logged in users? Currently it's using the "new style" - which most people will agree on is just awfully designed and I feel it is actively discouraging new users from contributing because of this. I'd like the default for new users to be Monobook on this wiki, since it is simple, easy to understand, and invites users to jump in and help editing. But for the life of me, I can't figure out how or where to set it. Any help would be greatly appreciated! - Zurgat: 17.42, November 26, 2011 (UTC)

 * Uhm, ok,. why would you say that? According to MediaWiki it is very much "possible", but the link / special page for it seems to be missing on wikia. - Zurgat
