To delete a knowledge entry, you once again have to mark its option button in the directory overview. Next, click on the trashcan button on the right-hand upper edge of the page. The system asks you a security question to make sure you really want to delete this knowledge entry. If you are sure you want to delete the entry, confirm by clicking the "Delete" button. If you decide not to continue with this deletion, you can leave the menu again by clicking on the "Cancel" button. You can only delete a knowledge entry if you also have delete permission for this entry.
