Hey guys,
Here is my problem. I have a website and after users register they will have there little member area. What I'm trying to do is after they register they can send a payment on paypal and this will give me more features. I'm confused as how to set this up.
I would like it to all be automated, I dont want to have to go through and check the paypal and then find them on my site and "flag" their account. Can paypal do this for me?

thanks for the input
