Add guest after public event registration closes

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

Open the existing registration in event administration and use its administrative Edit Registration/Add Guest workflow, select the appropriate ticket or package, complete the guest fields and save/review any price/payment change. This requires registration-edit permission and the enabled backend-registration capability. Public closure is different from administrator editing, but capacity, ticket/package rules and event state still apply. Do not reopen public registration or create a duplicate registration merely to add a guest; ask support if the authorized control is unavailable.
