I have been using PayPal for recurring subscriptions. I have since added Authorize.net AIM. If I disable the PayPal plugin so new users can't subscribe using PayPal, what will happen to my existing PayPal customers? Will they keep getting billed accordingly from PayPal? Will their accounts be canceled? Will their accounts last forever?
I would think that if you disabled it the reoccurring payments would break (?!?!) Aside from hacking the signup, one option until you get your existing users converted over could be to hide PayPal from the signup: https://yourdomain.com/amember/signup.php?hide_paysys=authorize_aim
