Yes, I understand. Unfortunately, because my book starts off as CC-BY-NC-ND for the first 6-12 months, it is incompatible with CC-BY-SA. Eventually, it will become CC-BY-SA, but at first it does not "share-alike". My publisher is already way ahead of the pack just by agreeing to CC, so I have to make accommodations. A CC-BY-SA doesn't work for me. It seems silly to re-create the entire glossary from scratch, so I'm hoping I can ask the 4 major contributors to give me a CC-BY for this particular use case.
