Groups define the areas of interest within your community. Some groups you will be able to join without requesting membership; others, however, you can join only by requesting membership or by being invited by the group owner.
The following table describes the group types and how you can join each type.
| Group type | How to join |
| Joinless | You are a member of Joinless groups by default. You do not have to request membership nor be invited to join by the group owners. The functionality available to you depends upon your group permissions. |
