Note: Only an admin can create a new List
STEP 1: Open your Workspace. If you do not have the link, you can find it from your dashboard: https://rocketium.com/w/
STEP 2: Look for the 'New List' button (always the right most option) and click it.
The new list is always added as the right most list in the Workspace. You can click on its name to edit it.
