Heyo, I run three membership sites using visiongateportal and paypal. The IPN is redirected to the first site and has special forwarding capabilities. But now how do I set-up my fourth site with amember? I asked this question before buying and they said it wouldnt be a problem. however paypal only shows you one IPN option and I havent gotten a response to my support ticket.
