I signed up and paid my $1.00, but the registration page to view my subscription asks for a mailing label subscriber number. I didn't realize that you have to be a print subscriber to get this offer. It should be more clearly stated and they shouldn't have taken my money.
Nevermind...I believe when the order is out of pending status, you can login by clicking on the TFH DIGITAL tab and then clicking on SIGN IN (PREVIOUSLY REGISTERED). I was able to create a user name and password after purchasing the subscription.
