AbigailII: True. Which is why I'm one of those that stands by that it shouldn't depend on an aggreement. If I want to autopass, then my opponent probably won't mind if I do, even if (s)he doesn't want to activate it on his/her side. In the end the game will play faster anyway and I won't have to open all those pages where all I have to do is click a submit button.

(the only exception I can figure out is for fischer clock games, where autopass might become an advantge)
