Yes, however, that will not work for what I need. Basically I am going to have teams created for this event. Each team leader (once registered) will be given a passcode to send to the other members of the team who will then need to buy tickets. I want each team member to have to use that passcode in order to buy the ticket (this will allow me to track how many members have registered to each team). If they do not have a passcode, then they can buy the ticket. Is there a way to do this with the Event Manager?
