Currently there's a way to update user role on unsubscription... does non-payment trigger the same action? And are there any plans to include the option of updating a user role on payment?
E.g., right now our client's site creates an account with the user registration plugin (with the role set to Inactive) and when users log in they are forced to a payment page (powered by the paypal plugin). We'd like the role to be changed to Subscriber when a paypal payment is received and set to Inactive when a payment is missed or the subscription is cancelled.
