Have you checked out Creative Common License yet?
If you or someone you know has just made an awesome song on a mac, or created a neat picture via Photoshop, or has taken a priceless picture on your camera, and decides to upload on the web and want some legal rights to it and let everyone know that it is your creation, you can. While you can also leave a note under your creation(which someone else can also do to steal your work), Creative Commons License offer a more sophisticated licensing to protect and let other cybernetters know that it is really you who created the work. With Created Common License you can : preserve your right, attribute your work, render your work non-commercial, or share it. It is free, no registration, user-friendly, valuable and covers many (videos, music, pictures, websites,) except software and inventions that require a patent. A notable contrast with Creative Common License and other Copyrights is that it is "Some rights reserved" and "All rights reserved".
