How to create a new role?

Go to Settings, User settings, Roles and add new or edit existing roles.

Authorized users can easily define many different roles, each with its own set of rules. To create a new role select the + button on the right-hand side which will open a dialog. In this dialog, you have to define a name for the new role and select rules. The rules are divided among several tabs for an easier overview. Select per tab which rules apply to the new role you're creating and click save. Now, this role will be available when adding a new or editing an existing user.
