Also, I think it should be possible to take one of your works, make a branch of it, license it CC BY SA, and make another branch from that original work and publish it under a different license. Not a legal expert at all.

Edit: sorry for necroing a post from 10 year ago, i thought it was on front page xD

Author can do whatever, it is just a question of "does it make sense?".

If you license under CC BY SA and CC BY NC SA, the later makes no sense as it's more restrictive than BY SA. Given these licenses are irrevocable and sublicense is compulsory, trying both makes no sense whatsoever.

Unless you have CC BY SA and CC BY NC — the later is not approved for cultural works and all that, but will find adepts. As Reid said, NC cannot be accepted. It is NOT OPEN SOURCE, goes against the project principles and is overall incompatible.

Once the author adopts CC0, he cannot recover control over the work. At this point, more specific licenses are irrelevant.

You can always contribute less restrictive licenses (Micksha licenses his works under MIT, Hocus does the same, I use LGPL for code and CC0 for everything else, etc.) but never more restrictive licenses.
