I just saw this in the documentation: WARNING. PayPal PRO does not support recurring billing, and it is by nature of PayPal PRO system. It cannot be implemented in the plugin because it is not supported by PayPal, and clearly denied by PayPal Pro terms. I want to make sure because I want the option of new members being able to sign up as a guest and not have a paypal account but I also need recurring payments as well. Thanks for any info on this!
