Is Content at BlueNC Copyrighted? And If So, Who Owns the Rights?

We're not copyright lawyers, but our impression is that if you publish something without stating otherwise, you hold the copyright to that content. Our default position here at BlueNC is that each author owns the copyright to their own content, and that's what the copyright notice at the bottom of the page says. Of course, each author is free to identify their own work as belonging to the public domain, or to choose a more flexible license for their own work.
