Sorry Blair, but you're confused. The pre-paid monthly subscribtions applies to International users. However, they can also sign up for regular monthly billing.
North American users can ONLY get the regular monthly billing at the moment. Yes Blair, I know Canada is in North America. Read the CAVEAT below:
Caveat: The server tries to figure out whether or are International or not based on your IP address. Sometimes this can be misleading. If you have a problem with misidentification along those lines, just email support and they'll help you get it straightened out.
Of course, hopefully they'll just cancel your account, because you're supposed to be banned.
