Every time I try the site on my iPhone, safari crashes immediately. I can share details by email.

Long version: we have a dedicated mobile version of the site but we never got around to updating that before the launch so we disabled it.. had some other issues too and the content was all outdated. So a mobile friendly version of the site will be built soonish. I just wish jQuery Mobile was here already so I could build it with that. :)
