Admin Forum:Manage categories, ... and about special page MediaWiki

--Kog981 14:06, January 23, 2012 (UTC)I just want to ask does we have any way to manage all the categories that we already created but in someway forgot it named?

And I want to ask too about how many special page MediaWiki we have?
