I’m looking for a group to join. How do I find it?
Go to the Groups Tab (second icon from the left, from the main navigation bar). From here, you can scroll through groups near you, and/or search for public groups by tapping on the search icon.
Once you find the group you are looking for, tap on it, and click the Join button. When you are a member of a group, you can see upcoming events, and receive invites, announcements, etc.
