Seems when you try to hit www.renderosity.com/index.php (the main home page), all you get is a blank page.
I was able to get in here through a link to my direct gallery, but even if I click on the 'Home' button at the top of the page, same thing, blank site.

Tried using windows with IE and a Macintosh using firefox and safari, same problem, on two separate DSL accounts.
