Oh, and forgot to note, it's not that I believe the author MUST post warnings, I just would hope that the author realizes that, in fanfiction, stories without warnings like that will make some of us very unhappy- and possibly poison us against ever reading anything that author writes. And the one author who wrote back to me, stating that she never put warnings on her fic because she felt that it gave away plot points, struck me as being an idiot for thinking fanfiction should be held to those standards. But, as I said, I simply put her on my "never read her" list.
