It does that for me as well, but, that is not a fault of the website. I use a screen resolution of 1024 x 768 as my vision is a bit poor. A higher screen resolution will most likely have the page properly centered for you.
1280x800 is my screen resolution. Haven’t had any problems with it.
mine’s 1680x1050 & the whole page is about 60% to the right 
it’s looking great though, I had seen screenshots of the early developed version.
Great work 
Yeah, it does that too on my FreeBSD box running 1280 x 1024. Agreed. The website looks great!
