A group is an area of Nextdoor where neighbors can share messages about a specified subject. Only members of the group can see messages posted in the group, or add new messages to the group. A group is a good location for messages that most neighbors do not want to read. For example, if you want to share messages about politics or sports, you can make a group for that subject.

A group can be public or private. When a neighbor makes a new group, that neighbor makes the group a public group or a private group. If the group is private, only the neighbors invited to join the group can be members. All neighborhood residents can join public groups.
