well you can always view it as an MPQ if you can read JASS. I noticed that in defiance, its a lot like how when you enter a cheatcode in singleplayer, the chat just doesnt show up after you press enter. However the game can still recognize it as chat (that's how the map boots ppl if they try 2 play an RPG in single-player and type in a cheat)..
Like for example, in single player, if you type "greedisgood", it won't show up as chat, but you'll see "Cheat Code Entered"... the chat event can still be used 2 recognize this and the chat string would still be "greedisgood". I sorta want it like that, but EVERYTHING that's typed just doesnt show up and i can make it appear as game-text instead.
