Review Accessibility Site?

A while back, I developed a site on Section 508 compliance for internal
use by our developers, and I think my boss might want to make it a
generally available resource.  If anyone has the time to take a look at
it and tell me if you notice any glaring mistakes I've made, I'd
appreciate it:
