Wikia has disabled editing in all MediaWiki recently, for security reasons. About a week ago some of the MediaWiki pages, such as CSS pages, have been enabled again for editing, yet the vast majority (including MediaWiki:Emoticons) remains locked (staff members can edit them, yet emoticons are mostly not important enough to bother them with editing requests).

Though, to be fair with you, it's about time for the staff to allow editing this page.. if not all MediaWiki pages.
