Factsoflife.com does anyone know who made that website it hasn't been updated since the end of its run on USA

I don't know, but it is the "official" site, and it should be updated !

There is nothing 'official' about that site, it's not officially endorsed by anyone involved with the show - it only has the domain name that anybody could have registered.. it was just made by a fan like every other FOL site.. it was I believe the first FOL site, made sometime in 1996..
