Because of the number of spam emails coming in through the "Contact Us" link, I have disabled email from those classified as "unregistered". If you cannot get registered for some reason, please post your problem in the "Registration Related Problems and Questions" forum, which does allow (at least for now) unregistered people to post. If we start getting spam in that forum, those few people that have trouble getting through the registration process will be left to resolve initial registration problems themselves.
