### Group Type

You can choose from a number of options which determine how other users may join your group.

#### Open Membership

Setting your group type to Open Membership will allow any user of the site to become a member simply by visiting your group page and clicking the join button.

#### Request Membership

Setting your group type to Request Membership means that any user can request to join your Group, however as owner you can choose to accept or decline this request. The requesting member will be automatically notified of your decision.

#### Invite Only

Setting your group type to Invite Only means that only users that you have sent an invite to may join your group.

#### Controlled Membership

Controlled Membership is only available to Administrators and Staff, and allows you to add and remove people from a group directly.

This is designed to be used for a course-based group where the membership is defined by an external system (such as an institution's enrolment system) and you wish to replicate that membership in the group.

Users cannot remove themselves from a controlled group.
