GenCon has published another letter, this time to its attendees. They are asking out our experiences with the local community as vendors and in general. You can respond to them by using the following:
Phone: 800-529-3976 (x3806)
I'll draft my response and post it as an update to this later. I loved my only GenCon experience and I can't wait to be going back!
Update: The Game Manufacturer's Association has also come out with a statement supporting GenCon's position.
