Each Service has an option to add a discussion for the people responsible for maintaining it. A discussion allows you to make comments on a specific service and make sure that they are all in one place and shared with the correct people.
Possible options for discussion include changes, versioning, or common errors.
To get to the discussion you must be either a Space Admin or the Form Developer role.
Discussions are available on the Edit/Configure page for a Service. If there isn’t a current discussion, you can add one by clicking the Discuss button on the far right.
