Forum:How do I prevent annon edits and diable account creation?

I'm a Bcrat at the FFWiki. Recently, a vandal has started attacking our wiki, and I can't make him go away. I want to prevent account creation and annon edits for a few days, just till it dies down. However, I don't know how to do it, or if I even can. Can someone please help me, I just want to go back to playing Rock Band instead of monitering the Recent Changes for an immature... Anyway, please help! Diablocon 18:27, 26 May 2008 (UTC)
