I have put up a little web site to house the resources I use for my
Linux Class at <http://jasonclinton.com/linux_class/index.xhtml>. Anyone
can access it; it's a work in progress. Everything on the site is public
domain. I'll put something up there eventually proclaiming that.

The site has mostly just the concept maps that I use as a teaching aid.
You may need to print them to be able to read them; none of the PDF
viewers I have can render them on the screen well. Concept maps are read
by following relationships between major ideas in the mind. It's a
graphical representation of a "schema" as defined by the field of
psychology.

Let me know if anything doesn't work.
