You can choose the feed, how often the feed updates (every 30 minutes by default), and how many items (5 by default) are displayed to your players in it's config.yml
Your players can look at the MOTD at any time by using the /news command.
Server administrators can force the feed to be updated at any time as of version 1.0.3.
Possible Future Additions
New command to force the RSS feed to update (added in 1.0.3)
Permissions (not sure why you would want that, but why not). (added in 1.0.2)
Change Log
V 1.0.3: Added the ability for the console or a player (with the permission node news.update) to force the RSS feed to update. Seem to have fixed the problems with java 6 compatibility
V 1.0.2: Added an info and infoOnJoin property to the config.yml which allows you to have a more info type dialogue before the news is displayed (which can be toggled on and off for the onJoin with the infoOnJoin property). I also adjusted the way that the message is sent to the players.
V 1.0.1: The prefix in the chat can be changed through the config.yml prefix property
V 1.0.0: Initial release, what you see is what you get.
