Create a Survey Group
Survey groups in LimeSurvey help you organize multiple surveys into logical categories — such as by department, campaign, or topic. This is especially useful for teams managing many surveys at once.
This allows an administration user to create a survey group. By default the user is the owner of the group. The owner has all permissions for the groups he owns.
