+  * Players can be remembered by their names and added to a list of remembered names - the "friends list."

+  * A list of "ignored" player names can also be retained.
+  * Ignored players will have their comments stifled in the given player's chat window.

+  * 0 - display friends list<br>
+  * 1 - add player to friends list<br>
+  * 2 - remove player from friends list<br>
