The utility of a group in surveys is to be able to share "administration permissions" of a survey from the "survey permissions" option. The group name should not be very generic and cannot exceed 20 characters. The user who has requested a group on the survey.uv.es platform in his request can ask us to add users to the group by sending an email to the address encuestas @uv.es with the list of authorized users. In the event that these users are not registered, they must request the account with the usual procedure explained in How do I request an account? What happens when I have already given "survey permissions" to the group and then a user is added to that group? One of the people who administer said survey must give explicit administration permissions to the user.
