E6 is getting outdated and the latest web designs donot look well in IE6. You may add this small javscript snippet in your web pages to show a warning message to the viewers to upgrade their browsers. The user can also close this message. Warning message will not be displayed in other browsers than IE6. The snippet is shown with the whole html page.
