I'm playing in eight different ones, and this is the way to go:
Start the game or scenario as an internet game, and allow others to join. The IP and names don't matter. The turn order is the way the civs are listed, from top to bottom. Start the game, pick your tribe, play your turn (make sure you have the "end player turn" feature enabled). When you see the "end player turn" flashing,
YOU MUST press Ctrl plus "N" at the same time, or the AI will move your fortified units.
Now go to where you nomaly save a game. You will see a new feature, the "password protect" feature. Click on it, give your tribe a password that's easy to remember (Important: Yopu must not forget this password, or your tribe is unusable), and assign it to your tribe. Now no one can look at your cities or mess with your units. Save the game with a simple name (Turn 1 w/your tribe name, and so on), and turn the game off.
DO NOT HIT ENTER, OR IT WILL START THE NEXT TRIBE'S TURN!
E-mail the save to the next player.
The save goes where you normally keep saves, in the scenario folder, or with the basic games saves.
It's very simple, and it works fine.
