I have organized many Secret Santa, Boo Buddies, Office parties, etc. and know that Admin surely has their work cut out for them on each and every GE. I know that no matter what you do or how much you try, you cannot make everyone happy.
I know whatever decision is made that Admin will make the most appropriate one that is best for the YT Community.
ETA: I forgot to add my opinion
I like the idea of having a max limit and a required thank you thread.
