how do I publish a new ros node or package?

edit

I've written a small ROS package and uploaded the source to a repository on github.

It's a package to provide some interfaces between ROS and the SIG EVO car racing championship simulation.

I thought I would then be able to then publish my package so that it would show up on http://www.ros.org/browse/list.php somewhere.

I had a look on ros.org for how to do this, but can't see it. Am I on the right track? Or should I add my node to an approved repository?
