IMO, if they wanted such an exclusive-ish party, then they shouldn't've been advertising it so openly.

I'm used to private parties at con being relatively discreet to avoid hurt feelings by those not invited.

This crowd plastered posters all over the con, with the restrictions in small type near the bottom. I certainly never noticed them until after we were turned away and I read one of the posters closely.

I don't have my Clear Ether with me to see whether they were included in the party list, but with such restrictions, they shouldn't've been.
