How do I handle copyright issues on a blog/CMS template Im developing and selling?
I deal with licensing issues every day. I’d be wary of editing a license since that often confuses the hell out of people. They think it’s the real CC non-commercial license for example since they didn’t read the small print that was changed. It sounds like you want a regular old commercial license. If you plan on making a living from selling this, talk to a lawyer. If its more for small change, consider something along the lines of a clear statement in you them / documentation such as: // Copyright 2008 deern the headlice // This theme requires a commercial license for use // See http://example.com/buy.html for more information I would also recommend doing web searches for that text, and also some other embedded string from time to time to see if people are using your theme without a license.
Copyright licenses are not magical talismans. Licensing your copyrighted works at one time will not void your copyright, and you can choose to stop licensing the work at any time. One option (as indicated by WizKid) is just to edit the CC license. Another is to go to the CC License and build your own.
