I'm not from Kindle, so I don't know exactly what their deal is for previously published versions and how they define 'exclusivity'.

I would suggest that there be an arguable distinction between the rough draft, and the final, and I would suggest that the Final not be available anywhere but Kindle Unlimited.

Then, maybe you can have your cake and eat it too?

Again, I'm not the one who decides that -- KDP does.

And no, I don't have any affiliate benefits for Scrivener, or Kindle Unlimited.

This is just a method for Mac to publish a novel, and a way for your community to step up its game and bring in readers onto HIVE and draw monetization in USD from one of the largest self-publishing hubs that exists.
