You must use one of the licenses listed on this page for your contribution when you make adaptations of material under BY-SA or BY-NC-SA and share the adaptation, unless your use falls under an exception or limitation to copyright. Below is the definitive list of permissible licenses for your contributions to adaptations, which depends on the particular license that covers the material you are adapting.</p> <p>Creative Commons evaluates licenses for ShareAlike compatibility according to its published <a href="http://wiki.creativecommons.org/ShareAlike_compatibility_process_and_criteria">process and criteria</a>. Any license that has been considered formally by CC under this process will be listed on this page, with unsuccessful candidates noted in a separate section.
