A text display is like a canvas that can contain many items of text. Each display can be seen by multiple observers (players) and each player can see multiple displays. For example, you could have a display that showed a score, and a display that showed information specific to one team, such as the location of the flag. Every player would be an observer of the first display and each team would have their own display that its players would be observers of.
