Hi, Guys -
Yes, Greenfield Games would be where I am aiming for. For right now, I will keep things pretty basic, plan for two 2500 point games for everyone, maybe write up a few specific scenarios. Sometime in March is looking best, as schedules seem to be tighter for people after that.
I could see trying to do some kind of larger scale multi-player battle at some point, though - maybe a bring-and-battle format where there is a set start and end time, and people can join in and/or recycle onto the battlefield. I am thinking of the first day of the battle of Gettysburg, where a small action kept escalating until everyone was fully engaged...
Lex - PM me with more info about your trip - if you are going to be on this side of the pond, maybe we can get a game in...
