This website only accepts exclusive membership and only complete idiots are allowed. Member should take a special IQ test and prove to be dumb enough to join. Once a member, people can share their stupid thoughts and pointless hobbies with other fellow idiots. Sadly, no matter how hard we try, many of us prove too smart to join. Once you successfully join the site, Not-mensa is really amusing and catchy.
