A friend asked me how does one "plus mention" someone in Google+
Although it may seem obvious I've been asked before so here are a couple of screen shots which I hope help.
On the desktop version you can mention someone in a post or comment by simply typing the + sign (or the @ sign) and typing there name.
You'll get some suggestions based upon your circles as you type, but you can mention anyone on G+ and they will receive a notification that you have "mentioned them in a post".
Note: Google made some changes recently about who can send you notifications so a person may not receive a notification depending on how they have notification set up.
