|Using community / Using social groups|
As a group administrator or member, you can invite people to join the group. Note that if you're using Jive as an internal corporate community, people from outside the community might not be able to join your group.
Any group member can invite any other user to join a group. If the group is public, then you can share the group with non-members. If the group is private or secret (also known as Private: Unlisted), the invited user must accept the invitation. A group administrator must then approve the request to join the group. If it was a group administrator who originally sent the invitation to the private or secret group, the approval is automatic. For more information on how a group's type affects the content visibility, participation, and invitation permissions for group members, see Types of Groups.
