Facebook Groups allow you to share info, updates and media with a small, closed group of people, such as your family, classmates or coworkers. Although Facebook lets your friends know when you join a group, the site does not notify you when someone leaves a group, even if you’re an active member. Instead, you have to do a little snooping to find out. Also, you have to be a current member of the group and you need to know that the person you’re looking for was once a member. Tips Writer Bio
