You walk up to a board in a social space and you hit whatever button to access it.
You then see three columns.
The first is the emblem and player ID of the fire team leader.
The second column is the description of what the leader plans to do along with requirements like a microphone or light level range
The third are the amount of players who have signed up with the fire team. A gold number in this column indicates that the leader has the amount of players they need.
The post is then locked and removed once that number has been reached.
Clicking on the post will expand it and give you the ability to sign up for the fire team. When you click on the button to sign up, you get a pop up notification asking if you really want to join. Press Yes to accept and the 3rd column count of players increases by one. PressingNo brings you back to the board.
