Just Listening mode

If you have a chat room if some people that doesn't want to hear ector, you can put it in **just listening mode** so he can learn while people are talking.
Alright I changed here.
Sorry for the bad code, I was running out of time here... =)

Did you understand now, what I wanted to do?
I want a function new function to make ector just listen to a conversation.
And keeping the same "shut up" function intact...
