Forum:Requiring logins to edit?

My wiki is Everybody Edits Wiki. It gets a lot of vandalism from IP addresses and I don't really like them editing because I can't keep track of who is who. How would I go about semi-protecting the whole wiki, and requiring people to log in before editing?  DBF 10:21, August 28, 2010 (UTC)
 * Your wiki is Everybody Edits and you want to prevent people from editing? Sorry, I just find that funny.  You should probably request help from VSTF. -- 11:47, August 28, 2010 (UTC)
