Is that supposed to link to something more extensive? Maybe an opt-out for the e-mail?

After you click your Edit Profile link, look up top where the "My Footprint", "My Music" and "My Stats" tabs usually are and there will be two different ones there. I can't recall the names exactly (my browser has been acting up tonight, otherwise I'd check for you), but if you click the right tab, you'll see your opt-out options there...

Thank you lankysob -- this is one instance where the banner really got in the way of site navigation -- even though the IA is consistent with the rest of the site, it just seemed invisible to me.
