If you're approved to sell in another marketplace, you can add that marketplace to your ScanPower account by following the steps below:
Hover over your name in the top nav and select "Account".
Click "Update Account Details" in "My Details"
Click the "Add" button next to the marketplace label, select the desired marketplace, and follow the instructions.
If you don't see the marketplace in the dropdown, please open a ticket with helpdesk.
