Conceding

players who concede just get a penalty...quitting stinks

Conceding and quitting are not the same thing. Conceding does not give you a penalty.

As far as I know, you now can concede 2 player games. (Which is what happens when someone brings up a 7 year old thread - everything has changed.)

Some people prefer that you concede, and some people prefer that you finish the game, and everyone is never going to agree on this, as the numerous discussions here and elsewhere prove.
