The difference is that the Fanfic mbs index doesn't host stories, Elflinn.
It's a list of the stories posted here on the mbs with links to where they can be found (their TOCs here on the mbs, whether they've also been uploaded to the Archive and can be read there, etc.) and other info (whether it's complete or still being posted).
You won't find any actual stories on the index site.
