I'm of two minds about this.
On one hand, if we throw together something at the last minute, and the Historicon people just squeeze us in to a closet somewhere, it will look bad, confuse people, and give the wrong impression for next time.
On the other hand...
I'll be at Historicon on Friday and Saturday. And I haven't registered a game yet.
So I'm "available"... sort of. BUT... I just don't have the energy or time right now to try to organize a tournament. And - odd as this may seem - I'm not really a tournament player. There are too many things I need to do at the Cons, for me to spend the requisite time in a Tourney. I usually have a lot of bizness to take care of, in various and sundry places.
I'll be happy to show up, say some encouraging things, and answer rules questions. And Who knows... if it's in 15mm I might even come by with an army, to play a game.
If other people want to set it up, and believe that they can do so, then just please make it clear with the organizers that you're not acting on my behalf. (Otherwise people will default to me, and I'll get dozens of emails with questions I can't answer.)
best,
Sam
