The manual is sort of incorrect in the description of how to play by e-mail. A link exists with the correct description, but I can't seem to find it. You might PM pgr or Ace. They are running a CW2 tournament currently and definitely know how. Mickey3D showed me how, but that was more than a year ago and I don't want to tell you wrong.
I'm the 51st shade of gray. Eat, pray, Charge!
