E-mail lists (also known as LISTERVS[TM]) are organized by topic of interest, such as the Foreign Language Teaching Forum or the "Elementary Education List." People with an interest in the topic can subscribe to the list to receive periodic e-mails. Some lists are read-only and similar to newsletters; others give subscribers the option to post to the list, which sends an e-mail that automatically goes out to all other subscribers. This article introduces the reader to e-mail lists and provides tips for getting up to speed.
