I assume this is possible. When I have a domain or when a person wants they can make it so that when anyone enters their domain there is a chatbar by default on the screen which supports domain wide local chat.
The domain serves the local chatbar by default, it is not up to the users to load a chat script but the domain does this automatic.
Is this available already, anyone else would like this to use in their own domains?
I myself do not like Voice chat and I want local chat standard by default in my domains.
