Why do the press/media items have to be approved? Who can approve them and who can make them visible?

The approval of the press/media items  guarantees that the items  are correct and that they may be used in reports, evaluations or other analyses.

You can check the information imported in your Pure profile (Does the news belong to you? Do you want to add more information such as description or relation with other research outputs?). You may also decide whether or not you want to make the Press/Media item visible in the UG research portal (changing the visibility from Backend to Public).
