Nice work as usual. Two comments.

#1 is that i dont see a Home page link in the navigation menu. Most of know that clicking the logo gets us back home but some people don't. I pay more attention than i should to UI design and navigation so maybe this isn't an issue for most people.

#2. I see the Newsletter link at the bottom and i dont see a contact form on the contact page. I think this is a great opportunity to build his newsletter contacts list by having a constant contact (or similar) form on the contact page. Every person who contacts sigsv will get put into his contacts list automatically.
