Mailing lists are electronic bulletin boards structured around a central topic or interest.
They are called mailing lists, because they are lists of e-mail addresses of interested people. Through a mailing list you are able to locate a group of people who share your interests. Each person subscribes to the mailing list, receiving copies of messages sent to the list. Subscribers or members can also send messages to the list, which will then be electronically distributed.
