Appropedia:Determining copyright status/Pages needing clarification

ISF pages - they gave permission, but do we have clear release as CC-BY-SA or compatible?:

• Plastics recovery manual 1
• whichever documents were translated from TEELTTECHNIEKEN-deel1-1ejaar.doc (ask KVDP)
• Original environment rehabilitation manual (emails from Reef Ball mention a desire not to have unqualified people editing the pages, which suggests they wouldn't agree to CC-BY-SA.).
