How many can attend the December 31 live video feed?

I had hoped not to need to restrict attendance, but may have technical limitations and be able to present the special Dec. 31, 11 a.m. New Years Eve Year In Review video presentation to the first 50 people who register for this free event.  So I've set the cap on registration at 50.  At the rate things are going, the event may "sell out" today.  If you are too late, you will still hopefully be able to register on a waiting list and if I can, I'll find a way to remove the technical limits on attendance (it is a free event, after all.)
