I’ve noticed I can add someone as a contact (pops up as a choice when I click on a member’s name) or friend (when I’m on a verified member’s page. I’m guessing a contact won’t turn into a friend unless I choose both. Is that correct? Any other differences? What does it mean when someone is a contact?

I’ve been a member of this site since the beginning. You’d think I’d have some of the basics down by now.
