When as admin I go to a user's profile and select the "Roles" tab I can assign roles in the "User" context. But it is not clear to me what a user context is. What exactly does it mean if for example I assign some user the teacher role in the context of another user? The help file does not help, because it does not mention the "User" context.
It is also not easy to find an explanation of this user context in Moodle Docs. However browsing the docs has brought up an example where a user context makes sense, namely for the "Parent" role. I nevertheless would like more explanation of this context.
