How Comentario permissions work
There are two kinds of permissions in Comentario: the superuser permission and a number of user domain roles.
Superuser is a system-wide permission that allows a user to perform any action on this specific Comentario installation.
A user domain role, or just role for brevity, defines what actions a user can perform on Comentario with respect to a specific domain. For example, a user can be an Owner in one domain, but a Commenter in another.
