Jay Kimble's blog is a good looking example of a custom skinned site.
Here is a good example of how to use a blogmap and some links to set one up.

I ran across a couple sites that have some great info on customizing Community Server.
After several hours I finally have my new skin finished. I tried to make it use div tags, but after several tries it didn't work out as planned. So I built it using tables and some CSS. I wanted a layout that expanded to use the maximum screen real estate. If anyone knows how to pull this off, please let me know.
