The header looks a bit outdated (I think it's because of the "bold" look). For your content area, add a different background color for your left and right panels to differentiate it from the content area.
I like the high constrast color scheme. I figure with the topic, you'll primarily be dealing with older people who may not be able to read all these wacky color schemes us young whippersnappers like to use. The body text seems haphazard. I'd suggest organizing it a bit more with headers, bullets, etc.
I believe it needs some css work and improvements. It does not a bit outdated. Maybe a different header would help a lot.
