Enrico's set of ten replay videos in the Video section will greatly aid you in learning the rules to this game.
I am unclear whether there is a Vassal type environment for the game.
It seems there is not a VASSAL module (Crap! I was hoping to play that online one day), but I guess I can`t help you either.
Failing that, you would need a pbem system. Who knows if anyone has done that yet. I don`t think this would be very difficult, just someone needs some Tuits to be able to get it done.
