How do I create self sign-up Groups?
Self sign-up groups allow users to choose the subgroup they want to be in. You can also limit the number of members who can sign up for each subgroup.
Note: You may have to change the group settings later if you want to prevent students from switching sections.
Complete Group Settings
If you want to require group members to be in the same section, click the Require group members... checkbox . This option is only available as part of a self sign-up group.
Enter the number of groups you would like to create . You can create more groups at a later time, if necessary.
You can also limit the number of group members for each group  to help keep your groups balanced. To limit a group, type in the maximum number of members who can be in a group. You can also use the arrows in the type field  to increase or decrease the number. Once the group is full, students will not be able to join the group. If you do not want to limit the group, leave this field blank.
Verify Self Sign-up
Verify your self sign-up group underneath the group title and group settings.
