Over the past few months, I've helped answer a handful of questions re: people wanting to set up a campus club or group in Canvas that lives outside of any course. The club/group isn't tied to any one course. For example, we have a Multicultural Club, an Auto Technicians Club, an Accounting Club, and a Chiropractic Specialist Club (to name a few) in our Canvas instance.
In order to set this up, you need to have Admin access to your Canvas instance. If you don't have this kind of access, speak to someone who is at your school. Here's what you get: Home, Announcements, Pages, People, Discussions, Files, Conferences, and Collaborations.
Here are the steps to setting this up:
Go to your Admin Pages (Managed Account) of Canvas.
Keep in mind that if you have the same person in multiple groups, it will be necessary to first create an additional Group Set (step #4) since an individual cannot currently be assigned to two or more Groups within the same Group Set.
