Site changes

The website has undergone some surgery. New layout. More consistent. Simpler for me to maintain. Should also be easier to find things and less stale info, I hope. Same style and implementation as the new site. There are still a bunch of old-style pages remaining to be converted from the FreeWay WYZIWYG site builder to the new scripted approach. I'll be tweaking things further, let me know when you come across links that don't work or content inaccuracies, please.
