[JASS] Lock the messages to Observers Channel

[Lestat(br)]

I'm making an investigation map, and I don't want players to be talking and talking all the time via the [To All] or [To Allies] channel. I want to lock the chat [To Observers], and convert it to a floating text in the unit's position.
I know how to do the floating text, but I don't know how to lock the chat to the observers. Please help me.

Its not possible to force people to only talk to the observers 'channel'. It is possible to hide all chat messages.
