subscription payment

Hey people
I have a really important question about receiving payment

is there some way that I can let my members subscribe for 30 days to a group in my forum and pay for this subscription through paypal?
so when the period ends the member will automatically be removed from the group!

is there any one who knows any solution??

May I remind you that double/triple posting isn't tolerated unless separated by 24 hours (Use the edit button)

Automatic way is not possible you have to remove & put him in manually.

Znode Storefront contains support for subscription payment processing and recurring payments. This provides merchants with immense value when deciding how to set up product pricing for their business.

Enabling subscription payment processing offers benefits to both merchants and consumers. By allowing customers to opt in for a recurring shipment, they can rely on an automatic renewal of consumable merchandise or subscription services. Merchants can increase customer satisfaction by offering the convenience of automatic delivery, without the need for customers to place additional orders. In this way, merchants can also take advantage of a guaranteed steady source of revenue with subscription and recurring payments.
