Server-wide Announcements

Server Wide Announcements (also known as the News Feed) are a feature that allows a player's accomplishments to be displayed to all other players in the Chat box. Certain messages are only broadcast across the server on which the player is logged in while others are displayed across every server. Any message is displayed to the player's friends. Messages that are server specific are displayed in orange, worldwide messages in red, and messages to friends in green.

A player's achievements are only displayed to everyone if they have their private chat set to on; they are displayed to any friend so long as their private is not set to off. On the other hand, players will only receive messages from the news feed if they have their game filter set to all.
