Multiplayer Play By Email Question

[HercMighty]

We'll I got my copy today and can't wait to get off of work. But I do have one question for the above topic. I understand that:

1. players make there empire files.
2. host creates game and sends out game file (and custom empire files) to all players.
3. players load game make turn and send player files to host.

Now this is where I get confused. Host has loaded his game and has finished his turn. Does he save this game to a different directory and move his player file to the main game file folder and then load that game and complete turn? Or does he load game as a player do turn and then load in as host and generate the game turn? I'm sure it's simple once I get everything loaded but 2 of my friends ordered there game and got it today to so we were going to try this tonite and the less questions I have the more fun we'll have. Besides everyone has been great with answering my questions!
