I do not have IE6 but have seen this error on Browsershots and other people computers. The whole Content area is not Justifying itself under the header right. It is putting it all the a way on the left.. It is also causing the RIGHT to go under the LEFT Sidebar, I am sure it is related.
I have seen this before, but have no clue how to adjust it without screwing it up in other browsers..
Any gurus, please help me discipline IE6!
