How do I add/change which branch(es) I'm assigned to?
Navigate to the Control Panel using the 'My Profile' option in the 'My Account' menu, then choose My Profile and select the edit button to make amends and update. You will be prompted to re-enter your password before making any changes. You will be able to change your primary branch, or add / remove secondary branches on your profile.
