You can do anything with your story - it's yours. The setting alone is not a part of the project from the licensing point of view, but some parts of it (like names) may be. If you're afraid of being sued for using your own outline - if you're the copyright holder, the only way you could be sued is by yourself.
Writing is not going forward at all, there are like three of us doing anything on a regular basis here.
Hey Q_x. Thanks. I'm not afraid of being sued, I just want to acknowledge that this project had an influence on me, I suppose. I'll make sure to update this thread if the story ever gets published.
