There's several places where the right border on the boxes don't appear in IE...and there's no padding in some boxes like especially the boxes in right.tpl and the path to images is wrong for the title section and this affects many of the .tpl files. The copyright for your site will be invisible because it's set for white text on white background. Your footer will also not be centered on the page. I hope you can get him to fix it. Good Luck.
