We're working on figuring out why they think we're spamming, but until then - if your e-mail address is with these companies:
sbcglobal.net
swbell
comcast.net
cros.net
prodigy.net


you'll need to register with a different e-mail address in order to complete registration.

I'd suggest getting a free gmail, yahoo, or hotmail account. We've had no problem with them.
