Moving towards better optimization, the number of background images on the site are being reduced. To keep form and function to point, this is being done by flattening the overall look. Many images have had minor adjustments to fit the updated style. Check the About page (link on the bottom of the page) to see how the site look has changed over the past years.
The updates over the past 3 years have been slight, mostly security updates and other minor tweaks and enhancements. The results should be a slightly more refined and consistent look and feel. More work to do... just not enough time to get to it all.
