Yeah, they still exist--I used to chat with HonorH all the time--they've just gone "underground," off of ff.net.
Generally, if you can find the site for The Official Fanfiction University of Middle-Earth, you can find them all, because the author of the particular "author fic" requires that anyone wanting to write about a fanfic U for another fandom HAS to ask her/his permission, and she/he has a list of all the fanfic Universities, plus links to the stories.
Or at least that's the way it was when I was still reading OBAFU. I even created the main OBAFU website for HonorH after the fic was kicked off of ff.net.
