As an FYI for admins who will be making sure they don't have a problem with the "make any JavaScript or CSS imports use the //www versus http&#58;//www syntax" issue:
 * Places to check for this are MediaWiki:Common.css, MediaWiki:Monobook.css, MediaWiki:Wikia.css, MediaWiki:Common.js, MediaWiki:Monobook.js, MediaWiki:Wikia.js, and possibly MediaWiki:ImportJS</tt> (unlikely).
 * Make sure to check any CSS or JS pages that the above might import.
 * I'm not sure, but https&#58;//</tt>somedomain might be ok (assuming it already works).
