Thread:Copyleft/share-alike (12)

Updates: recently updated the pre-amble to include:
 * a definition of "libre license" on the page
 * reference to "libre share" - which is not copyleft
 * (more like "one more step of freedom" - e.g. a derived work (or even unmodified copies) may be CC-BY if no other components disqualify CC-BY).
