Citizendium have just announced a CC-by-SA license. The announcement is here  and the founder's essay on why they picked it is here . I think this means we can now use all their stuff!
However, they are using 3.0 and I don't know if there are issues with that, so I'm commenting here rather than changing the actual Cooperating with Citizendium page. License experts, can you please update that? Pashley 03:57, 22 December 2007 (EST)
- But it's CC-by-SA 3.0, and CC-by-SA 1.0 isn't "any later version" compliant - correct? ~ 126.96.36.199 06:11, 22 December 2007 (EST)
- Answering my own question - creativecommons.org says: "version 1.0 licenses required that derivative be published under the exact same license only". ~ 188.8.131.52 06:43, 22 December 2007 (EST)
No comment yet, so I updated the page. Pashley 03:58, 4 November 2008 (EST)
