I have some questions about interoperability between Creative Commons licenses that aren't answered on the CC FAQ. I believe that my question falls on the simple/practical side of the line, rather than something tricky requiring actual legal advice. Is there a stack for this? (So far I've found the Law proposal, and I'm not sure if it's a good fit.)
Example question, Can I copy a CC-BY-SA 3.0 work and distribute it (unmodified) under CC-BY-SA 4.0?
