Jim,
The most accurate approach is to go to the (blue button) SIGN UP form and then enter any state that you wish. If a state is not currently accepted, it will tell you immediately (for example, Hawaii, Georgia, etc.) with a red error message. Otherwise, you are good to go.
This list of accepted states (over 30) is expanding pretty frequently, so we encourage players to check back if your home state is currently not on the list.
Thanks,
TG Jeff
