A mailing list is a list of people who subscribe to a periodic mailing distribution on a particular topic. On the Internet, mailing lists include each person's e-mail address rather than a postal address. Mailing lists have become a popular way for Internet users to keep up with topics they're interested in. Many software producers and other vendors are now using them as a way to keep in touch with customers.
How to Subscribe to a Mailing ListThere are an estimated 30,000 mailing lists that you can subscribe to. One way to find out whether there is a mailing list on your particular interest is to link to Vivian Neou's Search the List of Lists .
How to Set Up Your Own Mailing ListTo set up a mailing list, you need to put it on an Internet server . Often your access provider ( Internet service provider ) will help you set it up and maintain it on the provider's server, usually for a fee. If your provider doesn't offer this service, there are some other providers who will (see Vivian Neou's page for a list of such providers).
Vivian (she's written a book on this subject) also tells you about the process of subscribing (or managing subscribers) to a mailing list.
