The Blacklists are lists of pages to be excluded from certain features in the new Wikia skin. For example, the photos blacklist can be found at MediaWiki:Photosblacklist. There, administrators can list photos not to be shown in the Recent Photos widget. The other blacklist is the Categories Blacklist, which is found at Mediawiki:Categoryblacklist. There, administrators can list categories to be excluded from the Categories toolbar at the bottom of the page.
