How do I see inactive groups?

Use the Search filters at the top of the Browse Groups page to see Inactive Groups

By default, Inactive groups are hidden on the Browse Groups page (Groups & Events > Browse). Change the Active/Inactive filter located in the Search area at the top of the page in order to see inactive groups and reactivate them as needed.

You can easily reactivate inactive groups while still on the Browse Groups page by clicking the Activate button located on the far right side of the page.
