I play over wireless internet connection, and all users of my wireless network have the same external IP adress. There is one internet club on the wireless network, and there is probability that someone other than me could be playing this game from the same IP. I would like to know who I need to inform about this? Of course, I will respect rules of the game and will not trade with players whic live in my town, but neverthless rules say that I need to inform administrators.
