Not that I know of; but I always start with checking "self search" for stories people have sent me, so I haven't started looking yet.
Best place to check for anthrax stories that don't show up on the front page is *Anthrax_Scare_List.
By puting *Anthrax_Scare_List into the "reply to" box on threads relating to anthrax, we're trying to keep these stories cataloged so can all keep up when we get a chance :)
