Moderator for new users posting crap?

It seems like there's someone posting a load of crap about aion and socerers??????

is there a way to block new users? this could get a bit annoying......

I've banned them from the forum and deleted the posts. However, I can't see any settings to make membership be approved first so I'm not sure how long before we get more spam, I doubt this will be the last time.

Anyone know how to do it or if it can be done? Or any computer whizzes out there who know how to create their own forum?
