We have an unbelievable number of spam-bots who attempt to register for the forums on a regular basis, which is why we have an actual human (namely, ME!
If your email address and/or choice of forum name is a bit "original", and your application for membership is denied, feel free to resubmit your info. It's truly nothing "personal" -- it's just that your info appeared too similar to the spam-bots I deal with routinely. If you'll reapply with the same name/email info, I'll generally approve it the next time I see it... I just need to know that it's also another "real human" on the other end of that application, not just a persistent spam-bot!!
