"You cannot register with an anonymous e-mail address (hotmail, yahoo, gmail, etc.) unless a current member vouches for you. Just have them send me a message with your handle after you register. If no one here will vouch for you then you must use your Internet Service Provider e-mail (comcast, charter, etc). We do this to minimize troublemakers."
This is a good policy, one that I wouldn't mind seeing on tnet, but I don't know any GT fans... I'm a member on other forums like techsideline with out any complaints...
