" Does any of your clubs have club trainers? If so read below to be legal with the FAA.

Two solutions below have been approved by the FAA:

1. The easiest solution is for a club leader to place his or her number on all of the trainers. The club leader does not need to be present when the model is flying. If there is an incident that involves an FAA investigation, the FAA typically focuses on the “Pilot In Command” and not on the person who lent their registration number.
2. The club can use a disposable or replaceable label that is changed depending on the instructor or student. Some clubs use masking tape that can be easily removed. Other clubs use plastic and a dry-erase marker.

I thought the AMA's stance on registration was it wasn't clubs responsibility to check registration.. This sure makes it look like it is a clubs problem to deal with.
