How do I add an attendee to the event after the event registration has closed? I had people walk-in the event and I'd like to track their attendance as well as send followup email.
I can definitely see why having an accurate list of the walk-ins would be important. Currently once the event is 'closed' then it is not possible to add additional registrants. Unless you set the event to close early though, you should be able to add people right up until the end of the event itself, so you could have a registration form on a mobile-device for people to register as they arrive in the future.
