opponent has not returned a turn in a month

For what it's worth, BBrus has already stated the correct procedure. If you're about to reach the 21th day from your opponent's last turn you should:

1) Post a flare in the forum or send an email to your opponent CC-ing one of the ladder commanders.
2) If you don't get a reply after a few days and more than 21 days have passed, you are entitled to a total victory.
