I agree with dc0ded, header isn't looking that professional. I think fluid width would look better and consider changing the header.
IT is great. The content in it is very useful. You can change the theme which uses the full width of the page so that you make very useful things from it.
assuming the software works, it seems very useful. the site is fine for this purpose but I suggest spending some more time on the header, it doesn't really fit.
