Using IE6, please upgrade...
You want to avoid your site to have a bad reputation, because it doesn't render correctly on IE6, then just install this tiny little script (7.9kb).
During page load, if the user uses an outdated version of IE, the script will show a nice, clean and very polite message asking him to upgrade to a newer version of his browser.
The message shows a link to the latest version of IE, Firefox, Opera, Safari and Chrome.
