Multiplayer

I Understand that by using an FSXid with sim Connect and the simconnect add-on when a player joins the session, it will assign the player a specific FSX Id Correct? And If so how are you able to do that, There is no Sample data. Also.Would there be any way possible to access the Chatbox of a session with any SimConnect API or Any FSX API, if so is there any sample data?Much help would be appreciated
