We have received a few emails of people dismayed at having been spoiled for upcoming episodes by stories that did not include a warning up front.  So in the spirit of kindness towards your fellow readers, please DO NOT put any spoilers in the summary of your story.  In fact, DO WARN readers about potential spoilers in the summary, indicating the upcoming episode(s) which the story might spoil.  You may want to reiterate that warning in the author's notes as well.
