There is some module or code so that when someone new is registered, the last activity on the network appears and if you click on it, it will take it to your profile and it can be Followed.

In my network and in this one, if you are not a follower, you do not see the publications

What I want is that when a user makes a post, a message appears in News feed:

@falcone public a photo
@albertof public a video

The ad is seen by all users and if they are not followers who have the option to follow the user to see the publication
