Hi Bill, As with all free software projects, most of the initiative must be done by the contributor. Please find something that interests you in the project, work on that and send a patch when you feel you have something. The TODO file contains a list of things that we currently think are important.
By the way, the system that you have been administring for over ten years is actually the GNU system. Linux is a kernel that we use with GNU. Feel free to see http://gnu.org/gnu/linux-and-gnu.html for further details.
