In our team game, we have 3 allied and 2 Japanese players. Each side divides their commands up as they see fit. The first Japanese player runs the turn, and sends a copy of all of the files to all players, just like in a regular pbem game. The exception to this is the actual savegame file itself. He issues his orders and saves the file without hitting end turn. He then sends this file to the other Japanese player. That player opens the turn, issues his orders, then hits end turn. He then sends the file to the first allied player who issues his orders and saves without hitting end turn. He passes to the next allied player, etc, with the last one to issue orders hitting the end turn button and sending the file to the first japanese player who will then run the turn, generating the combat save and other files. By sending all of the other files out together at one time, everyone can go ahead and watch the combat replay and look over the combat reports. So it actually takes very little time when the turn arrives to process it and send it own. We have had several turns where everyone did their cycle in a 24 hour period. Even at it's slowest, we still make 2-3 turns a week.
Hope that answers your question.
