We currently use YourMembership.com and are looking to move across to WA as we feel if is more feature rich overall. However, as per YM, it would help if all attendees signed up for an event were grouped with the same batch ID. In YM there is a field in the export file which provides the same unique seven digit number for all attendees contained in the same booking. This is extremely useful for sorting exported data and listing attendees in order of group booking. It is also very useful when importing data in our seating plan software, Perfect Tableplan. Matching the 'Batch ID' to the 'Group' field in Perfect Tableplan allows us to view all attendees of the same group and easily seat them accordingly.
