You may have noticed the look and feel change of this site from a dark to a light content format.  The dark format is professional in appearance but not very practical.  It’s hard for my eyes to frequently switch between light and darker formats.  I’m betting if it’s tough on my eyes, it’s tough on the eyes of others as well.  Additionally, I upgraded the site to a wider 3-column format.  I may still make a few more improvements over the next few days but I hope you find these improvements welcome.
