I think it would be nice to be able to change the language that you say something in on the fly. My thought was to use ^ as the precursing character.
So I could type SAY }Halfstaff /quiet ^Gorbesh Hello! and I would say it in Gorbesh to Halfstaff without changing my currently-selected race.
Just doing SAY ^Gorb Hello! would obviously say Hello! in Gorbesh.
