I'm wanting to customise my WordPress to allow people to sign-up (or pay for membership) and pay for postings.
But the thing is, I really don't know where/how to get started in terms of integrating WordPress with Paypal/GoogleCheckout.
1) How do you integrate WP with PP/GC?
2) Are there any running website examples of WordPress websites that integrate Paypal (PP) / GoogleCheckout (GC) around? Even if the website no longer looks like a blog, I'd be interested.
3) What plug-in is best for PP/GC?
4) Is there a different approach to paying for memberships as to paying for posts?
5) Lets say that a user wants to pay for membership/post. How do you verify that they've paid BEFORE they start posting? Or is it a simply a case of putting it in a queue and waiting for confirmation of payment?
