Tutorial 7

In tutorial seven, the book starts off by talking about the unique way of sharing information known as a mailing list. A mailing list is a list of names and email addresses for a group of people who share a common interest in a subject of topic and exchange information by subscribing to the list. Mailing lists are not like the list of contacts you have with your email, but a way to ask a question or suggestion that gets forwarded by a server to subscribers of the list. Another popular user subscribed feature is a podcast. A podcast is a subscription audio broadcast that is created and stored in a digital format on the internet. Podcast became widely popular with the creation of the iPod.
