paypal gateway in membership plug in

Hi,

another questions about paypal gateway integration.

1. Since the reoccuring payment is setup in the member/user's paypal profile, can the user cancel the reoccuring bill from within their paypal account?

2. If so, then will it automatically cancel the subscription as well in the membership plug in? will it notify me if the customer manually cancel the reoccuring bill/payment from their paypal account?

Other thing-- How can I reply to my previous questions without making a new thread?

Thanks
