If you accidentally canceled your subscription this month and would like to reactivate, you can do so by clicking My Account > Subscriptions from the top menu bar.
If it's been more than a month since your subscription was canceled, you will need to create a new subscription using the existing account and email address. Depending on the subscription, you may need to rejoin a waitlist, but don't worry! We're working hard to activate members as quickly as possible and it's possible to be billed within hours of joining the waitlist if spots are available. 🖤
