I have a friend who was trying to sign up today and hit "submit step 1" but then interrupted the page load before it completed because he wanted to change something. He has not yet gotten his "BB team will be activated shortly" e-mail, it's been about a half hour since he tried to sign up. If he tries to sign up again with the same user name, he gets a "username in use" error. I've recommended he wait until we confirm whether or not his first sign-up went through before he tries to sign up again with a different user name.
