Actually, the way I got onto the site involved a link I found to one of the files. I just worked from there. My assumption about the mainpage was that it was an intelligence test. i.e. If you were stupid enough to try to pay that much money to get in, you probably deserved to.
I didn't find out about it being a complete smokescreen until a while later, after which I quickly worked out an elaborate story to tell people, involving potential refunds based on their behaviour and perceived contribution to the morale of the community. Shame I never got to use it.
