What are virtual channels?
You can use virtual channels to talk to other Players, Groups, or Channels. You can for example create a hot key to talk to a different channel. You can create a new virtual channel to talk to all members of a specific group. It is even possible to mix that all together. e.g. Build a virtual channel to talk to the users Fred and Bob. Now add the channel Public-1 and group Operators to the same virtual channel. Fred, Bob, all people are in the channel Public-1 and all members of the Operators group will be able to hear you.
