A mailing list is simply a list of electronic mail addresses of people interested in a particular subject.
Mailing lists can include as few as two people or as many as thousands.
The Internet has thousands of different mailing lists on almost any subject imaginable, including many involving disabilities. Organizations or even individuals can create and maintain new mailing lists if one doesn't already exist for a topic. Each mailing list has its own distribution address , which looks just like a regular email address. This administrator may be a real person or an automated list maintenance program. Once you subscribe, your email address will be added to the mailing list, and you'll start receiving messages from other list members.
