Today added value to my site and a way to make more money later and added push notifications. I am using OneSignal and it is free. It is one of the most used. This adds value to my property. If I do sell it later on I can add the buyer to the Application that handles the push notifications as an Admin and he can do whatever. I can not give him my account as it is tied into my facebook. Yet as an Admin he can do whatever he wants.
