Transmission Rebuilders Network International maintains an active online discussion forum for their members. But some members prefer to receive forum posts via email.
The forum software has the ability to send copies of new posts to an email address, so TRNi configured that software to send copies to their CCtoMany address. As a result, each new post is blasted immediately to all subscribers on the TRNi list. Subscribers can opt-in (subscribe) for email delivery or opt-out (unsubscribe) at any time.
