I liked the home page so much that I clicked on the header to go back to it, but the header is not linked to the home page. Also on the home page I clicked Contact Us link on the parallax post page and it brought me to Support Us page.
One last item: on Safari the radio buttons on the G-form are cut off slightly on the left side (looks fine in Firefox). I had a similar issue. Cant remember exactly how I solved it but I believe I increased the margin.
The site loaded crisply for me, so I might improve the resolution on the sunset image a bit – probably just less jpg compression. Most noticeable around the feed of the jumping kid – can see compression artifacts.
