This site uses frames and is designed to be viewed at 800x600 resolution. To reduce "clutter" you can hide the right hand menu by clicking "Hide Features" in the top right hand corner. Similarly, if you invoke the Site Map, it can be easily removed.

At 640x480 resolution, the site can still be adequately viewed, however, you will not automatically see the features menu or the site map. You can however, "grab" the very right hand side of the frame and pull it to the left!
