If self sign-up is allowed, you can also set or change the number of group members allowed in a group, but changing a member limit will apply to all groups in your group set. You can modify the limitations within an individual group, such as changing one group to allow a few more members than the other groups. However, at a later time if you decide to edit the entire group set and change the group set limitations, Canvas will override all member limitations created within individual groups.
You can also choose to delete a group set in a course. Deleting a group set also deletes all groups within that set.
In Course Navigation, click the People link.

In the group set, click the Options menu , then click the Edit link.
