With email, messages can be sent to many people simultaneously. The recipients can be separated by thousands of miles and receive the mail at virtually the same time. A convenient way of corresponding with many others is to join a mailing list. Lists allow people to communicate with a group of people who have similar interests and concerns. They can collaborate on work, and ask for help with problems or assist others.
Mailing lists are generally free.
PW NET in an example a mailing list. To initiate a subscription to the mailing list, the user sends a message to the list, known as a listserve.
