on torn their is a trade , global ,factions and company chats others are with your friends, but wouldnt you love to have a group chat in which you and your 1 or 2 friends having a conversation with each other and you dont want to share it with someone else else..........
this could be done similar that how you initiate a normal chat . there would be a new icon in a persons profile ,you initiate it and the chat opens, there would be a option "add a person to this chat" there you would add the the persons id and he joins the chat
