Objectives:

  1. Learn about Lists
  2. Learn about Listserv
  3. Learn about Listserv Functions
  4. Learn to Subscribe and Unsubscribe to a list
  5. Practice Subscribing to a list
  6. Practice Unsubscribing from a list

Lists

A list is a mailing list, maintained by a Listserv program or a person, of people who share a common interest and wish to communicate.

Anyone can subscribe to an unrestricted list by requesting a subscription to a Listserv mailing address. Any message sent to the Listserv address is duplicated and mailed to the address of every person on the list. Everyone can respond to the message with each response being sent to every subscriber by the Listserv program. The result is a running group conversation. There are thousands of list groups on virtually any topic of interest.

Caution: Be selective in maintaining subscriptions to various list groups, you can easily begin to receive 50+ messages daily.

If the mailing list address begins with the word "LISTSERV",
(example: listserv@ksuvm.bitnet) then the list is automatically maintained by a Listserv program.

Mailing list addresses that do not begin with Listserv are maintained by a real person.
(example: Kidsphere-request@vms.cis.pitt.edu).

Click on the "List of Lists" drop-down list to see some lists.

Listserv

A Listserv is a family of computer programs that automatically manage mailing lists, by handling the details of subscriptions (adding and deleting list members), storing documents for retrieval by list members, and distributing messages posted to the list.

As a list member, you can send a message to a central address (the Listserv's address). The Listserv duplicates your message and sends a copy to each person subscribed to your mailing list.

The distinction between mailing addresses of the Listserv software and the list itself is important.

The Listserv software automatically handles the details of subscriptions and mail distributions; the list is the group of subscribers holding a common interest.

To subscribe to a mailing list, you must send your request to the Listserv mailing address. Once you are on a mailing list, you use the list mailing address to post and distribute messages.

For example, suppose you want to subscribe to the AEDNET mailing list. (This list is an international electronic network for those interested in distance education.)

To subscribe to AEDNET use the Listserv address: listserv@alpha.acast.nova.edu

Once subscribed, to distribute a message use the listname (AEDNET) address: AEDNET@alpha.acast.nova.edu

Listserv Functions

Several different listserver programs may be used to manage mailing lists - Listserv, Listproc, Majordomo, and Mailserv.

    Each program responds to similar commands to perform such functions as:
  1. subscribing and unsubscribing members
  2. obtaining information regarding subscribers
  3. managing mail options
  4. setting up your mail delivery options
  5. developing archived files of documents that can be retrieved by list members and
  6. duplicating and distributing messages from any list member to all list members.

Subscribing and Unsubscribing

List Subscriptions
There are two types of lists, one that is managed automatically by a LISTSERV computer program and another that is managed by a person or maintainer.
(Censorship is permissible in manually managed lists since list membership is optional).

Each LISTSERV program (for automatically managed lists) and each maintainer (for lists managed by a person) has a unique mailing address. This is the mailing address used to subscribe to and unsubscribe from a particular list under that management of the LISTSERV program or moderator. Each list has a unique mailing address different from the LISTSERV or maintainers mailing address. The list mailing address is the one used to send a message to all members on the list.
How to Subscribe/Unsubscribe - automated lists (LISTSERVs)
Use LISTSERV address to subscribe to and unsubscribe from automatically managed lists.

Example: listserv@unb.ca is the Uniform Resource Locator (URL) address used to subscribe to the list "Sais-l", a forum for exchanging ideas about making science more appealing to students.

SUB (Subscribe) is the program command to request subscription to "Sais-l". Thus, you would send an e-mail message to "listserv@unb.ca" with a single line message of:

SUB sais-l YourFirstName YourLastName
How to Subscribe/Unsubscribe - Manually Managed Lists
Use the list name mailing list to subscribe to or unsubscribe from manually managed lists.

Example: "telecom-request@eecs.ndu.edu" is the URL address used to request subscription to the list "telecom", a forum for discussions concerning the telephone. Since you are requesting subscription through a human list maintainer, no program command is used. You simply state in the e-mail message that you want to be added to or deleted from a particular list. Thus, to subscribe to the "telecom" list, you would send an e-mail message to the maintainer addressed as
"telecom-request@eecs.ndu.edu" and simply state "subscription to telecom requested".
Sending Messages to Maintainer
To send a message directly to the person in charge of a particular list, use the mailing address form:
owner-listname@list-URL-address
Sending Messages to Other Subscribers
Once you are on a mailing list, to distribute a message to all list members, the mailing address form is:
listname@list-URL-address.
Thus, to send a science-related message to the members of the list "Sais-l", (Remember, this list is for science educators.), you would use the address "Sais-l@unb.ca", name a subject, then input your message.

Note: the address "Listserv@unb.ca" is used to request subscription to list "Sais-l".
The address "Sais-l@unb.ca" is used to distribute messages to list members.
Finding Names of Lists

How do you find names of lists? A listing of Internet mailing addresses of the lists can be obtained by sending an e-mail message to:
"mail-server@nisc.sri.com"

The message should contain the line:
send netinfo/interest-groups

Warning: The list of lists contains over 30,000 lines of text.
