If you are a scholarship recipient, you will need the "authorization number" issued to you by the scholarship chairman before you can complete your registration here. If you do not have an authorization number and wish to apply for one, go here.
You will not need a credit card unless you register for something other than the covered registration fees and CME's.
If you change your registration information after you have registered (adding family members, for example), you must notify the scholarship chairman before you show up at the meeting. Anyone who has not been approved in advance by the scholarship committee will be regretfully turned away.
