Divide for sides and then pick somebody for CinC to see the turn first and last as the only player to send and receive email turns from the other side, who gets reinforcements, transfer units to other cdrs depending on situation, settle any disagreements etc etc. At least for emails to keep the turn from being duplicated and one of the players not having his move saved. It will look like he didn't play it. My turn was skipped like that twice in one game.
