In order to change the appearance of the Service Center landing page, select your name in the upper right and choose Forms Management.

Once in your Forms Manager, select the gear icon to the left of My SeamlessDocs. This will take you into the settings of your GRM main page where you can begin adding your header image, welcome letter, and choose how forms and folders will appear on this page.

You can even customize the background image, header, footer, and add announcements or resources to the page.

Note: In order to make your portal pages appear, you must click on the gear icon in the very top left when you're first logged-in and click on Sub-Folders on the menu that appears and make sure the toggle is switched on.
