I think in the very early days there were options to select private games as well as public. I could be wrong about that however, since I have only played public games.
Maybe some of the other 'old-timers' would know, or Russ could tell us what happened to the private game option. My guess is that it wasn't used very much so it was dropped.

I can't seem to find the proper setting to make games private. Can anyone help?
any chat made during the game between opponents is always private - other people cannot view any of the messages made in game.
the moves however will always be open for public scrutiny
