Is there a way to make it so a person has to make at least one post in order to edit their signature? Lots of people are registering to my site and they dont post, but just have links to adds in their signature, some of them are things that are sex related and I dont want any of that.

Maybe something like this...

Thanks, but I still want active users to be able to edit signatures as well.

A free one: http://yaldaram.com/showthread.php?tid=1
