For users who are stuck with IE6 and are not allowed to upgrade the browser, I have added support for Google Chrome Frame. Read instructions here.

I have tested and confirm that the website works fully (and looks better) with Google Chrome Frame installed on IE6.

If you can't install anything at all, then you may want to use a portable browser on a USB key or in your home directory, which do not require installation.

IE6 and 7 are now thoroughly outdated, with IE9 just around the corner (it is "release candidate" as of writing).
