When parsing the file, the script will look for certain codes to make changes to the document. Codes are used most often as the insert a piece of data into the document like the players name, the name of the faction they are in, the name of a planet, etc. Whenever something happens in a game, an event is sent to the players that might be interested. Such happenings include loosing a planet, new players joining your faction, etc. When a player logs onto Faction Wars, a list of all events is shown.
Players can then click the events to get more information.
Most events also show up on the announcements board where everybody can read about the recent happenings. While players could also simply visit this board every time they logon, direct events get more attention, as well as some events not belonging on the board. Replies can be made on the announcements board, but that can be restricted by the web-designer. If you have access to the real source you can get more information by studying the it. In the example, I have restricted user to only replying to faction challanges to be able to set a date and time to play for example.
