I'm new to the game, so go easy on me.

Is there a way to make a tab for the chat so the only dialoge that appears is friend chatter?
Also, how can I make a private channel (or tab) for a group of friends on the same server (or can you do it cross-server as well?).

/CreateChannel ChannelName Password

thats to create the channel

then click on the gear on the chat window that looks like a circle/gear click add tab name it what you like

then you go to that tab right click it and go to tab options and choose the channel numbers/things you want it to show in that tab a new channel if you havent created any yet should be Channel 6
