• Remove div#body { text-shadow: white 1px 1px; } from your CSS. It's unnecessary because you have a white background, but it can hurt performance (marginally) and makes selected text difficult to read.
• Either improve your site to where it does validate, or remove the W3C icons.
• A number of sponsor graphics are stretched, the ACCC is almost unreadable
• More info about your robots would be nice
• It wasn't clear that "About Us" is an actual link as well as a menu 'category'. The similar "FTC Teams" link goes to an empty page, so the navigation is sort of inconsistent.
• I would personally lose the text effects on the header logo, and make it the same bright green as the "Subscribe for Updates" text. The beveling makes it look a little blurry almost, and is in contrast with the rest of the site's clean design.
