@EddieHinkle @Burke If you’re just getting started, it’s probably best to go to KDP print immediately, rather than try to use a system being eliminated. They are functionally similar.
KDP print is likely an okay replacement for Createspace and it looks like they have a decent migration process for existing books. Another option is Ingram Spark. I haven’t used them, but they’re growing in popularity.
The real loss here is the Createspace staff. They offered excellent service and accountability. Amazon’s reputation is poor on those fronts, which is why many authors are bracing for impact. Hopefully the transition is smooth!
