You may use any private domain to register, as long as you use the webmaster@ or admin@ e-mail address to sign up. We also accept internet service provider e-mail addresses, as well as work and school accounts. After registering, you can set a free e-mail address in your account settings, so you only need the non-free e-mail to sign up initially. This means that if you do not have access to your own e-mail, you also have the option of asking a friend or family member to borrow their e-mail address or have them forward you the registration mail (noting that they will be unable to register with that e-mail address themselves, should they choose to join in the future).
If qwest is only your phone service, then it is not your internet provider. If qwest is your internet provider, then you have a qwest e-mail address available to you.
