That's new to me..........I never had that with UnRated game. If anything, there are more options with UnRated Games, ie; you can make an Unrated game with the "Takeback option " -- as long as the game is not over, you or your opponent can reset the game to any prior position and resume the game from there !
I just played an unrated game and it said something like " chat is temporarily disabled for unrated games"
Is that in likelihood permanent ?
Are there any other rules that apply just to unrated games ?
