PBEM. Your choice of side and scenario. All optional and experimental rules.
Very Interesting. Your Choice, good pal! 
I am curious how you are planning to handle opportunity fire. are you just going to try to include notes in the log file? i.e. “if op fire, disregard rest of log and send back to me”.
My preference for op fire is to resolve it after all movement is done. It’s the chaos of the battlefield - you maneuver per orders but perhaps all your troops don’t arrive as planned!
panther 2010, I sent you a PM. Hope we can get a game going.
