Sorry if this is confusing.
I received notification in my Gmail saying someone added me to their circle and invited me to join Google+. I'm assuming Google+ allows users to find people by name or email address. That person doesn't have my email address, so I guess that leaves my name.
I'm not on Google+, so I don't know why I'd be searchable. I want to make sure strangers can't just type in my name in Google+ and actually be SHOWN my Gmail address or otherwise have me come up at all regardless of what it shows them. Is that possible?
