Andersp: I don't understand that either. In my humble opinion, a red message "Your opponent is using Autopass", just as the auto vacation message would perfectly do the job. You wouldn't be surprised by an offline opponent passing back every game to you in an instance, and everybody who wants to take advantage of it could do so.

And I really like pgt's suggestion of a "use autopass as long as I can't move" option when you own the cube - the chances that I want to offer a double get smaller not bigger when I can't move several times in a row, I guess
