Unique identifier for each event registrant
Currently, each registrant to an event is assigned a WA serial number that isn't unique to the event. Abetter approach would be to assign each registrant a number, starting at 001, for that event. This number is unique to the event, so it's really easy to print name tags and do check-in. Currently, we have to export the registrant list and manually assign a registration number to each registrant. This is error-prone and computers are better at doing this than humans.
