Because mailing lists operate in somewhat the same manner as electronic journals such as MCJournal, many readers who have subscribed to this forum are probably already quite familiar with the concept of lists.
Lists facilitate information sharing among groups of people with common interests.
It is simply a list that contains the electronic mail addresses of all subscribers. An accurate count of the number of mailing lists is impossible to compute. A conservative estimate of the total would exceed 5,000. It is sometimes entertaining to examine the header information in list messages that traverse between Bitnet and Internet and note the convoluted paths they travel through gateways. Another common listserver software package, ListProcessor, was developed by Anastasios Kotsikonas of Boston University for Unix platforms and is increasing in use throughout the Internet.
