There are fans, at Haven and at Fandomonium, myself included, who are actively trying to save fan fiction sites and move them to other hosting sites, or at least save the content. Most, if not all, individual site owners who could be contacted have been contacted, and asked if they are planning to move their fan fiction to another free or paid site. Now we are working on the many specialty archives and rec sites, going through them individually to see if their fic is already archived elsewhere, documenting where and so on. But there are many other wonderful, squee-full, happiness-inducing places that will be gone for good if we do nothing.
I will not lie. This is hard, time-consuming, frustrating work. If the number of invalid email addresses is any indication, the number of sites that have been abandoned by their owners is large. But there are options out there. If you are the owner of a resource site in need of a new home, the Organization for Transformative Works, through their Geocities Rescue Project would like to help you. If you are looking for a new site to house your fan fiction, you can get an account at Archive of Our Own.
If you are not the site owner, you can help by suggesting places, with their links, to the OTW archive, Fanlore, so that they can at least be screen-capped for archiving later. We are not the only fandom at risk in this situation so the all-volunteer OTW is getting a bit overwhelmed. If you have some time, or even if you have to make some time, your efforts would be greatly appreciated both by today's fans and future fans as well.
Please PM me if you have questions or want to help. This is my fandom. It used to be yours, I do believe. Maybe in a tiny piece of your heart, it still is. Thanks for your time.
