When a registrant logs back in to make a change for a member of the group or to add other options, I would like them to have the option to -reissue the confirmation emails associated with the current status. During the original group registration there is the option for each attendee to receive a confirmation email. After might have a set of courses that have been changed for an attendee but only the biller receives the change with the complete details. You have the option to manually resend the thank you message on the back-end... but when you are dealing with a couple of thousand attendees... you prefer the registrants have this option. Also you get the "I lost my invoice" messages and this would alleviate some of that as well.
