User blog:DoctorBleed/Question about publishing rights

This post is particularly directed towarrds the moderators/administrators of this site.

I'm making this post because currently I'm trying to publish a collection of my short stories on Amazon Kindle. Currently, my book is blocked due to copyright concerns with KDP, with the fact that many of the stories are freely available online serving as another complication.

To publish my book on KDP, they need to verify that I have sole publishing rights to these stories. I notice many of the stories I've posted here are labeled "Creative Commons." I have to ask, does that disqualify me from having "sole publishing rights?" If so, I would like the license to be changed so that I can profit off my intellectual property.

Thank you in advance for any help you give me.
