This administration screen show the different roles a user account can be assigned.
All useraccounts which are assigned to a certain role can be viewed below the roles section.
New roles can be added by clicking 'Add new'. Creating a role this way requires you to manually assign all the required authorizations for the role.
An easier way of creating a new role is clicking 'copy'. This copies the selected role with all the assigned authorizations.
For the new role the authorizations not required can simply be deleted.
