Does the site's home page validate? The site's homepage validation returned 6 errors. All 6 were instances of Duplicate ID causing 6 warnings ass well. There was one additional warning due to an unnecessary role.

How would you rate the site's design, on a scale of 1(horrible) to 10 (fantastic)? Why? I would rate the design for this site at a 8 out of 10. I really like the layout of the site and the uniformity across the pages. I took 2 points off for the grey on black color scheme that makes some of the text difficult to read.
How would you rate the site's usability on a scale of 1 (horrible) to 10 (fantastic)? Why? I would rate the usability at a 9. The site's pages offer side-bar navigation which is very convenient, but the home page takes a minute to navigate.
