    I don't know how friends work on here, but I know if you follow someone, they can put post up that you will see in your notifications. I have quite a following on here, and when my Mr. Connor passed away, I could tag all of my followers to make sure they got the announcement.

      Following is when you are follow another members only or when that member is following you only. Friends are when you are both following each other.
