body: I have some idea of story, which I want to publish online (idea, not story, because it doesn't exist yet). I want people to discuss it and get some feedback from them.
  
  
  I asked [question](https://worldbuilding.meta.stackexchange.com/questions/4812/is-my-story-protected-by-copyright) on worldbuilding.meta, but here I want to ask if I publish it on some website (for example discussion forum).
  
  
  How can I protect my idea from stealing?
