Explorer Centercode Email Notification

Hi, I haven't received any new emails for any new Centercode programs since last summer. I think my email address was somehow removed from the email mailing (unsubscribe link by accident perhaps). I sent an email to ring@beta.ring.com twice to help re-subscribe but got no reply. I've emailed explorer@ring.com and no response either. Is there a moderator who can look into this?
