In posts there’s a green circle outlining my user icon and some, but not all icons. What does that represent? That I’m super cool? Or the opposite? 
Could it mean that they’re online?
I’ll close my browser for a few minutes, will you check and see if that’s the case? i’ll be back in . . who knows I get pulled away from the computer by family on the weekends
When I look at your icon at this moment, there is no green circle.
It means that you’re currently online.
Thanks guys, looks like we’ve figured it out…
