Payment is set as an amount per member. Someone registers during the earlybird discount period and sends their check in. It gets marked as Paid at the earlybird rate and they are Active. After the earlybird period expires, they decide to add a member to their group. They log in, edit their regsitration, but upon adding an additional member, it applies the regular rate to ALL the members instead of just to the new member. Now they have the new member, plus an additional balance for every previous member who was paid. I am not sure if this is a bug, or rather just how the system is. Can anyone else confirm this behavior?
Still looking for a solution here... so far the only thing that I have come up with is to not let them log in to edit registrations but then it puts more work on the guys that manage the conference. Often people register ahead of time not knowing who they are going to send, they just want to get the early discount rate. Then they fill the names in later. Obviously they will see the price changing on them and it will appear that they owe money even though they paid already.
