When guests are added to a registration, they are NOT currently required to have an email address. I understand that this is because the person doing the registration may not know the email addresses of their guests. (Well, they SHOULD!) This creates a problem--if you have chosen to add guests to your contacts, then you are stuck with useless contacts that count against your contact limit. SUGGESTION: If I choose to "ADD GUESTS TO CONTACTS" then the system should REQUIRE email addresses for guests. If I don't choose to "ADD GUESTS TO CONTACTS" then the system should NOT REQURE email addresses for guests. Just a note: Whoever is registering folks should have their ducks in a row and KNOW that they are going to need some basic info before they start--like email addresses.
