Community Lists are great for creating a personal or public ranked list like your favorite DC comics, or reading orders you want to track, and other shareable content.
To create a Community List on the website, go to your profile and then select Community Lists. You'll find a Create a List option there.
To create a Community List on the mobile app, go to the My Comics tab (middle) and then tap My Community Lists. From there, tap the add (+) button at the top.
