How do i report cheating?
Sort:
I believe that Karcher3 cheated in my game with him. When I played the game back on my computer, it predicted his moves towards the end of the game. At the outsetl, I believe they were his own moves, which is how he gets away with it. Thanks
I'll find the link: It's in the second paragraph. Oh you might want to remove the suspects name from your post; it's considered "naming and shaming" and you could get sent to the principal's office.
