After the recent dashboard update, I see that the email address linked to my XBox live account flashes across the top right of my dashboard, alternative with my Online Friends/Messages/Gamerscore and my GamerTag. Can people on my friends list (or everyone) see my email address, or has the GUI just changed to show it to me only?
I've looked at the privacy settings, and checked out some friends profiles and it doesn't seem this information is exposed, but the dashboard has lots of different views and menus, and I'd like to be sure it's not in there somewhere that I'm not seeing.
