Collectives™ on Stack Overflow are dedicated spaces where developers can find content that's organized around an area of technical practice or a technology provider's product suite. Defined by tags, a collective brings developers together to collaborate and learn from one another, as well as connect with subject matter experts from the community and the organizations that help build or maintain a technology product/service. Content includes questions and answers, as well as technical articles authored by Members of a collective, and bulletins – timely, useful, and relevant updates published by Admins of a collective.
Collective Admins can also grant users specific permissions, such as posting and approving articles within a collective, recommending answers that are associated with a collective, and having a user badge that highlights their role within the collective.
Any registered user can join a collective. Collective Members will see activity indicators when a collective has new content (Articles, Bulletins, Collections, or relevant Discussions). Members can disable these indicators per collective in user settings (Access > Your Collectives > Show new activity).
