browser switch campaign

I have just added a message to my website,, notifying WinIE users that their browsers will not render the site correctly as the site uses PNGs with alpha transparency.  I then give them a link explaining why they should not use IE and the benefits of upgrading to another browser.  My qeustion is has anyone ever done this and what was their experience.  I would like feedback and comments.  Why isn't their a browser switch campaign like their was a browser upgrade campaign by
