Participant Access

We would only like to have the presenter and registered attendees have access to our Virtual Meetings held one to two Tuesdays a month. Each session is different and accessed by that days presenter and those who register for the event. Our registrations are processed and paid through our database/meeting file. Once I have a list of registrants, how do I give just the registered attendees and presenter access to the event. We would prefer that once they receive the URL that they be required to log in using their email address and Member ID which we assign. If that is possible, how do I upload or give the list of registered attendees to Adobe Connect so that participants and presenter have access to session?
