So I looked at my site on a mac today and what I thought might happen did! The layout wasn't all it was cracked up to be in all the Windows browsers. The sidebar was not in alignment, so I started to rewrite the whole site layout in Strict XHTML last night.
I'm also going to use a version of this layout for the CF MoBlog. Oh and for all the BlogCFC lovers out there I am working on a CF MoBlog plug-in for BlogCFC. Should be ready in a month or two.
