It would definitely change the diplomacy angle, but not sure if I like it. It is a worthwhile suggestion that merits discussion of the pros and cons.

It would make it easier for pretrucers to communicate their strategy with each other without anyone knowing, although I imagine that they could be using instant messaging in another window to do that now anyway.

I think that it would definitely encourage more trucing, which I don't really like.

I think that I am against it for those reasons, but other ideas may convince me otherwise.
