Hello everyone: I have a doubt with subscriptions on paypal. I know that, when a user has a paypal account, his subscription status is maintaned at his paypal account, and when his period is about to end, he can pay using the services that paypal offers, and the IPN sends a POST to my servlet, that's ok. However, I don't know what happens with a user that hasn't a PayPal account, how can he pay his monthly service?? , does the IPN "knows" which user is paying so it is still able to send me a POST with the same data as if this client were a PayPal account owner?? Thank you very much in advance
