T here are thousands of electronic mailing lists, each specializing on a particular topic.
Where e-mail is a message mailed specifically to one or more individuals, a mailing list is a group of people where all messages from any member of the group are automatically sent to everyone on the list. For each mailing list there is a particular mailing list server which manages that mailing list. All messages are sent to the server, which then relays them to everyone on the list. Mailing lists are electronic mail discussion groups or if you prefer, electronic pen pal clubs , that exchange information among groups of people who share similar interests. You can participate in ongoing, interactive discussions with people from all around the world using electronic mail.
