I finally redesigned SwitchPortMapper.com so that it's more than just one ugly cluttered page. It now has several pages -- hopefully more informative and better organized.
This redesign was my first real serious use of Expressions Web. I'm not used to CSS, so it's taking me a while to get it working right. I have a new respect for those who can build fancy sites with CSS.
I still want to improve it with some additional graphics, but that will be in the next revision.
