Thanks for the great info.
I followed the steps in the Audience section, plus unchecking a whole bunch of other options elsewhere for sharing things, but when I view my profile as "Public," I don't seem to be able to see a "Restricted" label on my account, and I think people are still able to add me to their Circles.
And you also have only an About section under your profile picture/wallpaper, whereas I have About, Posts, and Collections (showing nothing yet since I haven't posted anything.)
Know of any other settings to take care of these? I looked all around, even deleted and recreated the account.
