User blog comment:Sarah Manley/New themes for the Monaco Skin/@comment-184532-20100331011200

@-Ascension-: If you're an admin, on the skins section of preferences you'll see a section at the bottom called "Admin options", you can choose a default skin for the wiki that will show to anonymous users and users who choose to prefer admin options (another checkbox on the same page). If you choose custom, it will go off the customizations in MediaWiki:Monaco.css - You can see Help:Customizing Monaco for more info on that.
