Repeat registrations by the same email

In GiveCampus Events, available controls depend on your permissions and the interface used by your institution.

The Events registration flow does not enforce one registration per email or automatically block a repeat purchase. The same person may legitimately register additional attendees, and guest identity is not an authenticated uniqueness check. Direct already-registered people to their Manage Registration flow for additions and make that guidance clear in confirmations/invitations. Review registration/payment IDs before refunding an accidental duplicate; do not assume two registrations with the same email represent an error. A mandatory duplicate-email block would be a product change, not a event setting.
