Titles recognize the leaders of the group. They are a powerful way to incentivize people to step up and support the group.
An admin can grant a title to anyone in the group, whether they are a member or an admin. Everyone with a title is prioritized on the top of the members tab and receives the title next to their name on their profile.
To grant a leadership title, navigate to the member's profile and press "manage member" under the three-dot menu.
