I figured that, but didn't want to break any rules--thanks for answering. Do you charge for your KDP-enrolled books here (via unlock), or do you offer them for free?
FYI to authors whose books aren't in KDP, but are for sale on Amazon: one of my books is price-matched to $0.00; I consulted with an Amazon agent and they confirmed it's fine to post the story here in serial format since it's not enrolled in KDP.
