Sorry to bump this question again- I'm just curious.
Don't use difficult words simple developers need to look them up

Main chat will be 'city-wide'. This so that new players willl not think nobody is talking, while keeping down the spam.
For public chat that is for all to see there will be the /p command.
For local chat the /l will work (with animation of talking).
Also there is the /w for whispering, /s for shouting.
There will be a 'radio channel' only for cops.
And there is going to be the phone.
For our 'banana lovers' the script has been improved. In the 1.2 version some talk was possible when under banana rule. The new version allows almost nothing.
