That is true, the game does not tell you to send the logs and they are not required. I'm not exactly sure which log is which either but they are all so small I just zip them all up.
Where do you put the turn files that are sent to you from the individual players? When you 'process' the turn what files do you send to the other players. Is there any way you can send the players a text file containing the victory conditions and game settings?
