It has been brought to our attention that someone has made a site (http://www.ultimatehpfanfiction.com) and taken it upon herself to archive what she deems to be the best of HP fanfic. Unfortunately she has chosen to do this by copying stories from other HP web sites and posting them on hers rather than just archiving links.
It is important to note that this is not plagiarism; she has credited the original authors and promises to comply with requests to not host stories. However, at SIYE we believe you as the author should have the final say as to where and how your stories are published. We also believe that a better way would have been to contact the authors concerned, allowing them to opt in rather than forcing them to first find out about it and then opt out.
We encourage you, our authors, to go to that site and see if your stories are posted there. If they are, it is up to you to decide whether you're happy for her to continue hosting your story. We recommend that you ask to have your stories replaced with a link to the story in its original location. That way, you retain full control of the story - changes, updates etc - and of course it means you still get the reviews.
Do be polite, though - she has at least tried to do it the right way, even if it hasn't quite worked.
