This can cause some confusion at first. When the judge replies to your emails, especially when you submit your moves, always check to see if it has found any errors. A typical error comes from confusing a fleet with an army. If the judge says there is an error, you must clear the error flag or your moves will not be processed. Of course, if the error caused an order to be ignored, you should resubmit the order correctly in addition to merely clearing the error flag.
Every player has a dedication rating.
Every turn has a deadline and a grace period. Get moves in on-time, and your dedication rating goes up. Miss the deadline and your dedication rating goes down. Furthermore, if you are so late that you exceed the grace period of a game, you will be kicked out of the game, be stripped of LOTS of dedication points, and you will find it very difficult to join another game. For more details on reading a game listing and understanding when the deadlines will fall, you should send get deadline to the judge.
