fanarchive is developing a multifandom fan fiction archive to preserve fan fiction works and, if need be, to defend public access to fan fiction in the face of possible copyright litigation (hopefully to be avoided). I'm excited about this project (it intersects with my fandom, intellectual property, and information science interests), but I invite you to check it out and make your own decision.
There's a summary of the project's goals here:
