There is a place, I think when you click share, it will ask you if your notes can be read by only your friends or everyone.
I remember clicking everyone since I am an online artist and want people to see my links where I sell my art, including traditional Catholic greeting cards. If anyone is looking for a Traditional Catholic greeting card custom made with names and such let me know, no obligation to purchase. It is through zazzle and I only get 30 cents commision per card sold, so I am not trying to get rich. I do this to promote the Traditional Catholic Faith.
Getting back to FB. try the share button, or your account, to change so eveyone can see, sorry I don't know exactly where that feature was, but it was not hard to find, I do remember that.
