I'm sure this has been covered elsewhere, but I've been in deep denial about the change. I couldn't face it directly with actual investigation and clicking things.

  1. What is a "host," and how does one become one? What does it mean? What can hosts do?
  2. What does that little blue check mark beside someone's avatar mean?
  3. What are "pending discussions"? Are these the same as greys? What makes a discussion no longer "pending"?

Anyone know? Your help is appreciated.
