Connect with your Drupal administrator(s), who is responsible for updating your department page. You can find who your administrator is here. Provide your administrator with any instructions and content needed for the update (photo, video, writing, links, etc). Every department is responsible for keeping their page(s) up to date.
If you are the Drupal administrator, you have the ability to make many edits directly on your managed web pages. Drupal how-to videos are available here. If there are edits needed that you are not authorized to do, or to request a new page, submit a ticket to the Help Desk. For content strategy assistance, reach out to Marketing Communications.
