Fraser,
I love the new look! The pages are much cleaner and easier to read.
I tried submitting your prototype page to the W3C site for validation, but it got hung up on the lack of encoding type instructions. Try going to
http://validator.w3.org and entering your prototype page URL and you'll see what I mean.
It's worth your time to fix this as a validated page will work much better in most browsers.
Looking forward to the new site!
Cheers,
EagleUK :P
