My feedback would be to point out advanced section tends to attract more writers than roleplayers. The big difference in those demographics is that writers need far less direction and structure to help advance the story.

What you have there looks very cool, but you don't want to bog people down in mechanics. In excess, it changes the target demographic away from your writers and storytellers and more towards roleplayers and tabletop fans who prefer working in a GM led, very structured environment. You probably have a good number of writer type people interested here from the way the first-post is structured.
