/XMPP!

Yesterday, we successfully configured /xmpp on our server. XMPP allows you to chat as if you're in-game, while you're offline. It also allows people playing the game to send you messages. Facebook uses an xmpp client for their chat. So does Google Talk, and Jabber. You can quickly set up a free xmpp account at jabber.org. For more information on how to set it up and use it, see here: essentialsxmpp
