How about if admin could configure during races only cars on track can use chat? (or even opposite, dunno why, but why not). In some race events there is a rule that spectators should not chat. So far this has not been possible to configure into the game.
Then someone asks: what if after crash driver specs, and he is not able to say sorry or something, because he cannot anymore chat after spec. Maybe there could be a max number of words/characters a spectator can use in chat, to overcome that kind of issue? Or driver could chat N-seconds after spec?
I know this is not top priority suggestion, but I think this could be very easy and fast to implement. I searched old messages if there is similar suggestion, but didn't find one exactly like this.
