I don't really want anyone to co-author my story because I don't want multiple writing styles mixed up in the same story. Also, I don't trust anyone enough to let them have nearly full authority over the story. However, I would like someone to read the story and give me suggestions for improvement. I need a revisor more than I need an editor.
What I'm asking is this: Is there a way to allow someone to preview your storygame without posting large amounts of pages to a forum, publishing the story before completion, or allowing them to be a co-author? Also, would anyone be willing to revise what I've written in my storygame so far?
