For whatever reason during the past few weeks, the forum has been bombarded with spam.
I am still looking into possible solutions. However, in the mean time, I have made the CAPTCHA image much more challenging for new user registration. (that's why the site was down for a few minutes today)
I believe I have deleted most of the spammer accounts. If you guys find one, either use the report post option, or send me a PM with a link to the SPAM.
Thanks for your patience,
Jason
