A note on our editorial policy: before publication we may edit the story for length or readability. However, we always remain true to the spirit of the story.
Why do we say that? First, we want to make it clear that, unlike many other online 'zines, we edit stories. Everyone one of them. Sometimes this means cleaning up a few typos, but many times it means a heavier edit (e.g. cutting unnecessary parts, clean up awkward sentences, resolving minor inconsistencies, etc). We do this because we want to make stories the best that they can be, and very few authors write a perfect story start to finish.
Do we review these changes with the authors before the stories go to print? Absolutely. The authors are usually pleased with the edits and recognize that they make the story stronger. If an author disagrees with an edit or two we're usually willing to change it back or make further modifications to address the issue. The important part for us is that the author is professional about the editorial process. But we do take the position that we have the final say on what we publish. If the author is really unhappy with how the edited story looks, he or she is free to withdraw it at that point, but that has never happened.
I will share one example of what I view as an unprofessional approach. In a recent slush submission, one author stated in the cover letter that he would "let" us publish his story "on the condition" that we published it "as is." I sent it back unread stating that we'd never publish a story on that condition. (Okay, maybe if you're George RR Martin). In my opinion, the world needs authors AND editors to create the best possible product and make the reading public happy.
