{{Main|List of Facebook features#Groups}}
Facebook groups simplify processes and protect the privacy of users when they interact with people.{{dubious|date=February 2020}}<ref name="NewsDemon"/> Users can create a group and delegate admins. Group admins are able to make a range of adjustments to the group page, such as changing its cover photo, moderating posts and comments, and pinning posts so that they permanently appear at the top of the group page. Admins can also create group events, news updates and manage group members. By default, groups are public, and anyone can join them at the discretion of that group's admins. However, groups may be marked as private — a user may only join such a group if an existing member sends them an invitation. A single user is capable of joining a maximum of 6000 groups.<ref>{{cite web|title=Facebook groups|url=https://www.facebook.com/about/groups|website=Facebook|accessdate=27 October 2014}}</ref>
