i already have a backup plan ready.. when the user sign's up you give them a complimentry "email account" accesible with a different password in the support area ( hidden away the same place the "cancel my subscription " is now )
sort of like how epassporte has its own email system so when a surfer signs up for bangbros.com he will get a free
[email protected] account , then the company can control how the user see's the confirm rebill/cancel rebill
