Oh, your post says "If you defect and your opponent defects, you neither player gets a point." Somehow, I read that as both players get a point. You should change that too for clarity's sake.
KK, will do.
Well, actually I thought it was clear (aside from the typo).
You're a sup mod, if you wouldn't mind would you change it to how you think it makes it more clear. I'm not really sure how to reword that.
