Here's how you can add a showcase to your profile:
- From your profile page, click on "Collections." (If you don't have any collections yet, click on "Create your first collection.")
- You'll see a list of all your collections. Beneath each title there's an option to "Make this your showcase." Just click on that link, and your collection will be featured as a showcase on your profile page! You can change your showcase as often as you'd like.
