Join a group Demonstration: fictional people and data; illustrative screen transitions. Open the group invitation or scan its Q R code. Use the Sign in or Create account button if prompted, then confirm that you want to join. If you have a code instead, open My groups, expand Join a group, enter the private invitation code and select Join group. The group page highlights the next event. Use the Events tab for upcoming meetings and the filters for past events. Joining a group does not reserve a role.
