The primary organizer of a Meetup group pays for their own organizer subscription. Every Meetup group must be led by a local organizer with an active subscription plan; groups without an active organizer will close after 14 days without a named organizer.
If you have an active organizer subscription but are not the primary organizer of a Meetup group, your subscription is not supporting any Meetup groups. You could use your subscription to start and organize your own Meetup, or if you want, you could simply cancel your subscription.
