                    When a user purchases a 
membership package, the release of benefit is automatic? Either the administrator needs to verify and approve?
If a user buys an 
ad, the release announcement is not automatic! I need check, at Paypal, if you really paid! 
Therefore, I ask: 
is there a system that automatically checks whether the user made the payment correctly?  ..."I presume, a system linked to Paypal, or other payment system". Is this possible?
