I continue seeing references to a international F-20 class, but I am unable to find a webpage.

I found: http://www.formula20.org/ but it's a defunct webserver.

http://www.f20.nl/ is the dutch F-20 homepage, but it's in dutch The rules I found there are so simplistic I cant help but like them (look under "reglement").

Does anyone know where I can find a set of class rules for the international F-20's?
