We're experiencing some mail server probs right now, so that's why the e-mail verification system hasn't been working the last couple days. Other mail functions such as thread subscriptions are also screwed up. Sorry for the inconvenience!
Thread subscriptions and "E-mail From Thread" functions have been temporarily disabled. Tech support still hasn't responded to the mail server problems.
E-mail verification system is in place once again. It seems to be working now. I'm still working on getting the "e-mail from thread" and thread subscription features working.
