Paypal Integration and Recurring payments
 

Guys-
i have set up an account with paypal. I have set up recurring payments (I think) on the vbulletin. I have selected the test button on the vbulletin options and it tested paypal "Successfully." ,-was the result.
But now i am looking deeper into paypal and i am wondering do I need to do more or is vBulletin set up completely.
i am thinking maybe other less organized sites might need more paypal integration than we do. OR (as might be the case) am I wrong.
Can I stop here? I do not want my first paying subscribers to fail, or worse their (Recurring payment to fail)

Manythanks.
