@TheDoctorFF - That's incorrect I'm afraid. No, they don't have to get our permission, unless you've explicitly changed the license of your stories.

Everything here is released under CC BY-SA unless otherwise stated. This means that, by releasing your stories here, you have already given permission for anyone to use your story, as long as they give you proper credit and share alike (they don't even need to ask you to use your work, since you've technically given them permission already)

People can change the license of their story to CC BY-NC (which means it can't be used commercially) or CC BY-NC-ND (which means it can't be used commercially and no derivatives can be created), which force movie studios to get permission first. We don't support licenses other than those (except public domain, I guess).

The question of whether (morally) people should be consulted before their stories are used is a whole other beast, but legally, no-one needs to be consulted (if they've not changed the license).
