I am following a couple people on beam ng, I don't seem to get any notifications when they post/respond to different threads. so I was wondering what happens when I follow a person. (this sounds vary stalk-ish)
Simply put good sir, nothing of note; following a user provides them with a notification that you have followed them. That, and a few settings within your profile privacy page is the extent of its functionality.
Thank you kind sir, I have no knowledge on the subject so I dearly appreciate your kind words and generosity to answer this in due time.
It does mean that their posts show up in Your News Feed (accessible from the profile drop down menu) as well. We don't get notifications from that though unfortunately.
