The demo site for this GetSimple theme is here
I didn't design this site I just adapted it for Get Simple.
The designer included loads of useful stylesheets for including all kinds of content. I wanted to set up a demo site showing how the theme might be used.
The Demo has detailed instructions for using and customising the theme. In particular different ways of making the third column and the footer areas editable.
It isn't all there yet. A work in progress.
