The Shoujo-Ai Archive was an archive and forum for yuri/lesbian fanfiction, created in 2001. When its founder died in 2007, the site was rescued by the Yuriba MUSH managers.
But after seven more years (and another death) even the mirror domain stopped working. The website remained accessible for a bit more, though, so here's the last copy I made in August 2014.

(Note: Attachments were originally missing; allattach.zip has everything I could scrape out of web.archive.org, but around half are probably lost forever.)
