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.
