Add something to the code in the forum that makes it so you can't put a link in your signature until you have 15 posts or something.
It's getting old seeing a response to a thread that says something like:
"I agree! Brad and Angelina should adopt more babies and buy the iPad 2!"
When it has nothing to do with anything, but they always have a little hyperlink in their sig leading to some product they are pushing.
I tried posting this in the top section of the forum, but couldn't, so figured maybe here would be good.
