MasterPage Switching
Ha, this button does nothing really, but why don't you try opening this exact page
in a different browser i.e. switch between firefox and IE, then you will notice
the change. Infact, open up two browsers at the same time, one in IE and one in
Firefox. The same page will look different. Neat stuff!
Style Switching
If you are in the firefox lay out, Click on the Blue Theme and Green Theme links
in the side bar to experience cool style switching
.... and you have now been officially style-switched!
