In a community, what initial step is taken to set up Chatter Questions?

To set up Chatter Questions in a community, the initial step involves adding the Question action to the global publisher layout. This action is essential because it allows users to post questions directly from the publisher component, making it easier for community members to engage and contribute to discussions. By placing the Question action in the global publisher layout, community members can create and share questions seamlessly, fostering an environment of collaboration and knowledge sharing.

While configuring user permissions for Chatter, establishing a Knowledge base, and creating a dedicated Chatter group are important aspects of managing a community, they do not serve as the initial action required to enable Chatter Questions directly. Permissions ensure that users can access Chatter features; the Knowledge base provides resources for answered questions, and Chatter groups allow for focused discussions, but none of these steps activate the specific functionality for posting questions in the community. The addition of the Question action is fundamental to initiating that capability within the Chatter interface for community users.
