Since ThemeShaper supports some plugins, I thought perhaps support for a CC-license would also be nice. Another option "Show CC-License" with a checkbox would make it perfectly easy: If the checkbox is checked and the user filled in the URL of his or her relevant license, the thematic post-footer would also include a small CC-button or simply a CC-text with a link to the license. I think even the letters "CC" would be enough...
Especially for use as a CMS this option would be of great help!
(BTW: Is there something like a todo-list where one can have a look before posting suggestions?)
