More than one roles can now be assigned to registered users. The portal defines two types of roles - primary and secondary roles. Every registered user will have a primary role which was assigned during registration, and then other roles can be assigned to him by the portal administrator, these roles are called secondary roles.
After the user logged into the Portal, pages displayed will be according to his primary role. He can switch to other roles assigned to him by clicking on the roles tab that appear on top of the portal's page. The pages displayed then will be according to his selected secondary roles.
