I have got the latest in my series of Dreamweaver extensions relating to Web Standards and inspired by The Web Standards Project, completed.
This one gives Dreamweaver users a quick way to add a message to their pages, viewable only to those with old browsers, which explains why the site looks shonky to them.
It has been submitted to the Macromedia Exchange so I wait to see if it will be approved and added to the Exchange. In the meantime you can download it from my Dreamweaver page, any problems with it let me know.
