I wanted to ask one question, I think I'll get a quicker answer here.

All of us set up a "thank you page" after payment is complete. Does Paypal send any data to that thank you page through form possibly?I just need to make it automatic, at least can I get user's ID on that page?

thanks,

N_F_S,

you will want to checkout the paypal IPN system, Instant Payment Notification, i believe you can make it call a url and post data to that url. not 100% sure of how that works as with clientexec it sends a callback url to bring them back to my billing and once successful it auto marks the invoice as paid. In any case I should think with IPN you will be able to script up something to do what you need.
