When anyone purchases diagrams from the NTGreek In Diagram Series, they are also entitled to receive FREE updates. An additional fee is never charged for any updates, whether for a collection or diagram set.

The diagrams are periodically updated to reflect corrections and innovations in diagramming style. Therefore, it is strongly encouraged that everyone purchasing a collection or a diagram set to join its specific voluntary opt-in notification service. An email is sent ASAP after an update has been uploaded to the server.

Furthermore, by joining the notification service, no one NEVER receives any advertisements to purchase something. Many voluntary opt-in services are thinly veiled scams to fill up email boxes with flyers to buy something and/or sell email address to associated vendors for profit. I think this tactic is wrong. The sole purpose for this service is to notify those interested when a new update is available. It is that simple.

All notifications are sent out as plain text. With every update notification, the subscriber has the option to unsubscribe from the service. Instructions how to do this are always supplied at the end of every email. The Notification Service is a safe, closed-loop opt-in subscription. Your email address will NEVER be disclosed to a third-party for any reason. This means that I will NOT share, sell, or rent your email address or other personal information without your advance permission.

As may be observed from the example below, only an email address is required either to subscribe or to unsubscribe from the voluntary opt-in service.

If you have already purchased a collection or diagrams sets and have not subscribed to this free service, then head on over to the Notification Service and join today!
