This page used to be a bit of a rant on the importance of Copyleft. Now, Creative Commons is readily available and has a whole website explaining itself, and providing great licenses so that we can share safely, happily, and productively. The links below are the licenses that apply to everything on this website, unless it's been published elsewhere and has left my control.
Also the site design is a modified version of the CSS from David Herreman
