I just got an email from Red7Media, the folks who recently bought Folio magazine from Primedia. And Red7Media says it is shifting Folio to a controlled-circulation model. I followed the link in the email and renewed my subscription to this bible of the magazine world. Check your email in-box and do the same. If you believe the "Act Now!" tone of the email, then time is short. "...we plan to hold the rate base to its current approximate 9,000 subscribers, we are encouraging our present subscribers to sign up immediately," Red7Media says. "Once the 9,000 is achieved, additional requests will be wait listed."
