What's the green circle around my icon represent?

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? :frowning:

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…
