It was only a matter of time before the forum got hit by spammers, there were a bunch of spam posts this morning that I deleted. As of this morning I have implemented a spam protection module that shouldn't affect registered users, however, unregistered users will need to fill out a captcha (one of those random word pictures), before posting. There are a few other protections in this module that will hopefully solve the problem for now. If it continues to be a problem then we will need to require registration before posting.
