Need Paypal Return page to show registration

I have s2member pro and using paypal pro buttons to let the customer pay for a recurring subscription before they create their username and register. They are sent an email with a link. But, I am finding that about 20% of my signups never register because their email must be going to spam. It is alot of work for me to continually try to reach out to them and give them a new link. Is there any way to fix this? I want Paypal to take them to the registration page or link.

Hi Eric.

The user would normally be able to register right after the payment, if he wasn’t logged in. The link in the confirmation email is just another way.

Could you post the all the log entries related to the transaction not allowed to register right after payment? x’ing out any private info (e.g. email) [hilite path]Dashboard -› s2Member® -› PayPal® Options -› Account Details -› Logging[/hilite]

Thanks!
