Google+ group?

Anyone actually join this? (If you don't know what I'm talking about, look at the top of any board on this site)
I don't see any google+ things on the top of this site, and I just unblocked all scripts on this page. Where exactly is it?
For example, http://cplusplus.com/forum/lounge/

Right above the "Welcome to this Board" thread.
No, I have a Google+ account but only about two people I know use it, so I gave up. Now it has an old and embarrassing picture of me on it.
