Multiplayer servers are now up and running for Minecraft. To join a multiplayer game, simply register for a free account (if you haven't already done so), log in with your user name and password, then click on any of the currently open servers to start building. You can use the T key to bring up the chat interface, or press the escape key to regain control of your mouse cursor at any time. Easy as pie.
