My site simplifi3d.com was running lucidCMS for quite some time now. While it did its job, I wanted a more flexible CMS that truly allowed me to separate style and content. CMSMS does just that, and now I have just finished converting it to power my site. I'm still learning this thing inside-out, but please let me know what you guys think.
I have a similar comment as Patricia, your site is not very elastic. If I max out the fontsize (sometimes I wish to read the screen from 3 metres, usually 1.5) some text spills over and the collumns are very narrow. But on both sides there is plenty of free space. Why not let the browser itself figure out if there is enough room for two colums side by side or if they should be stacked?
