I have tried the standard solution for paypal (with a button). I see that a customer paies and AFTER that he's required to register for the website. I don't think this is a great solution so I would like avoiding this.
I would like customer to be registered BEFORE the checkout. What it's not clear is... how s2member understand that there is a link between the user logged-in and the person who made the payment ? I know that with s2member pro you can use a single pro-form that does all the job... but how do you do that without a pro-form ?
Oh my God, I hope my question is clear
