The Creative Commons (http://www.creativecommons.org) is devoted to expanding the range of creative work available for others to build upon and share. While technically they use copyright to do so, the creative commons has this neat symbol that looks just like a copyright (00A9) except that it has two letter c's inside the circle instead of one. Thus, it looks like (cc) instead of (c). There are some other symbols they have also created which can be seen on this page: http://creativecommons.org/license/
Without getting greedy, I'd like to propose the adoption of the (cc) symbol in whatever way would be most expedient (so that creative commons authors can identify their work more appropriately), and leave for later the question of the other symbols. I am posting here first, as suggested by the website, to initiate discussion, and if there is discussion, following it through before making a formal submission, which if discussion warrants, would be the next logical step.
