Hi peterdai. Welcome to Insiders! You have a couple of options when it comes to enrolling in a status challenge. The fastest and most efficient way is to call the Rewards Customer Service line at 1-800-321-7396. Or you can always reach out to one of the Community Managers, AndrewT, deannad, lindseyh or myself with your Rewards number and we can begin the enrollment process for you.
