[Fate]

You do not need to hit any "save" button. The only truly necessary file (I believe) is the fthrland file (which is on the server). From this and the .2h order files the clients send the servers the server generates .trn files to send back to the clients (I believe this part is the same for IP and PBeM games).

As the server you should now have this game among your list of saved games (as if you had played it locally). To play it more you simply need to start the server up again and give it the same game name (if it finds the save it will load that instead of starting a new game).
