In the past, all registered users had the ability to Move pages. This left the door wide open from 2006 onward for copycat, serial page-move vandals to disrupt the project. Not anymore. Moving pages is now restricted to admins and those with the new pagemove rights (this was my doing, not a change that occurred with the new skin).
If you've moved pages in the past, and have established a trustworthy presence here: take a moment and read pagemove, then just post a self-nomination at Wiki 24:Pagemove/Nominations. Nobody who is a good community member and nominates themselves will be disenfranchised by this new change. 11:56, December 7, 2010 (UTC)
