You must register with a credit card to use this feature of the web site. You must also complete the ENTIRE transaction.

After you have registered and indicated how many people will be attending with you, a page with a button that says "Proceed to Payment" will appear. You must click this button and input all your credit card information. If you do not perform all the transactions, you are not registered!

You will receive two receipts: one will list the names of all the people you registered and the amounts paid. The other one will be a receipt for your credit card transaction.

If you wish to pay by check, return the form you received in the mail with your check.
