Membership Sunscriptions + Paypal

[Guest]

Hi,

I am setting up a membership site within my exsisting website.

I want to set this membership site up with subscription payments.

I am using PayPal IPN(and set up Paypal to do the auto return as per Markscart guide)

The ipn is all ok

Obviously when the Paypal auto return goes back to the confirmation page.

How can i ensure that when someone has paid the subscription fee, that they are sent sent directly to the members area to the sign on page?

Or is there a mod to help me to do this ?

Thanks

Julian
