1) The PayPal Pro Forms – is this only for PayPal Pro? I see a lot of stuff referencing ‘Pro Forms’ in S2member pro and I don’t know whether it is speaking about PayPal Pro or Pro Forms within s2member.
We call s2Member’s PayPal Pro Forms (as well as Authorize.Net Pro Forms) just “Pro Forms” in the forums sometimes. We’re generally referring to these:
Dashboard -› s2Member® -› PayPal® Pro Forms -› Membership Level # Forms
This is the only way to integrate with all the features of PayPal Pro that s2Member supports. You could also use PayPal Buttons for limited integration.
See: Dashboard -› s2Member® -› PayPal® Buttons -› Membership Level # Buttons
Also, can I embed the registration form into another page? iFrame or better?
Do you mean on another website, or within your site? You can only put Pro Forms on your site, but you can put them in any Post/Page. Just put the Shortcode into your Visual/HTML Editor. :-)
2) Have you guys found unequivocally that greater conversions/sales occur when a person pays for membership then registers VS registration then payment?
I haven’t personally seen any numbers on this. I’d recommend asking the Community Forums. :-)
