We currently use community groups to track student-led clubs on our campus, however, because of the nature of these continuous groups, we do not maintain a historic record of group membership once rosters are cleared for the next year. We use community groups specifically because we can allow our students to manage those groups autonomously. We'd love to see some permissions added to activity sections that would allow students to be activity leaders and maintain the ability to create and post content without simply being content editors.
Please see K12OR-I-2805. It seems many of us have a need to allow students the autonomy to lead an activity group not just a community group.
