Cool site! One thing I found: it can be that you didn't make a "success" page from your contact? I got a 404 when hitting 'send'
I have to tell you that I've had huge problems with my own contact page & only yesterday managed to get the thing to work LOL
You'll have to ask a Major or General for advice on it!!
I got a little side-scroll but nothing that put me off - good job
