We (http://sleep.fm) redirect IE6 users to an older version of the site that has less features.

Not sure, if that's suffice for this campaign or not?

Do you make these users aware that's what you're doing, and that their experience on the site would be better in a modern browser?

I think the point of this campaign is to make IE6 users aware (if they aren't already) that they're using an obsolete browser.
