Just a reminder for anyone publishing using Amazon’s Createspace: they will be automatically moving your Createspace account over to Kindle Direct Publishing in the near future as the two services merge.

This probably won’t affect me much since it just moves a completed book, but if you are in the middle of the publishing process, pay close attention.
