Many websites talk about subscriptions services or RSS. This is FREE and simply makes it easier for you the user to get the information you want from numerous websites without having to keep visiting the site all the time to check when new messages are online. For example, I could post a message and photo on Thursday and you might have visited my site the day before, found nothing new and then not visit again till Sunday night but if you were subscribed to eddx then this information would automatically show up in your subscription program or “feed catcher”.
