Introduction to E-Mail Discussion Lists

*** Skip Intro ***


The purpose of any discussion list is the exchange of useful information by E-Mail.

A Discussion List is an online community of people who discuss a specific topic or topics by E-Mail. You can find over 70,000 discussion lists on everything from Archaeology to Women to Business. List members join a list by subscribing to it, usually by either entering their E-Mail address into a form online or by sending an E-Mail message with a "subscribe" or "join" request. Every person subscribed to the list will receive the discussion by E-Mail. Members wishing to participate in the discussion send their message or post to a central address where it is then distributed by E-Mail to the entire list.

Moderated Lists

A "Moderator" is an individual who has volunteered their time to acting as a list policeman. They can also be seen as a large filter that catches all non-pertinent material posted to the list and kills it before it reaches the list members. The flow of information in a Moderated list is as follows:

List member submits post to a posting address

Post is received by moderator

Moderator evaluates content of post

If post is pertinent and meets list posting criteria, it is distributed

If post is a spam or commercial ad or irrelevant, it is killed

A killed post is a reflection that the post was off-topic or did not meet the criteria outlined for posting to the list

A moderated list is highly desired by list members because all information they receive from the list will be well-filtered.

UN-Moderated Lists

An UN-Moderated list means that there is no list moderator, and that any post sent to the list posting address is automatically distributed to all list members. The majority of lists on the Net are not moderated because moderating a list is extremely time consuming. Most unmoderated lists do however have a list manager who oversees them. If a list is interesting and on-topic, it is not only because of the content posted by the list members, but also because the moderator or list manager is doing his job to keep it organized. A moderator's job is also to continue or kill discussion topics as he sees fit and to step in and redirect the discussion when it appears to be straying off-topic.

Most unmoderated lists have a List Manager who is monitoring the list to make sure that discussions remain on topic and posting criteria are followed. If a list member posts an ad to the list or a post that is obviously just a self-promotion, list members are likely to make that person well-aware of what they have done. This can get very embarrassing, considering that there are upwards of 6,000 members on some discussion lists. It pays to read and abide by the List Manager or Moderator's rules, for it is their list. Those on an unmoderated list (or a moderated one) who do not take heed to set posting criteria may find themselves removed by the list manager and prevented from rejoining the group.

Many people feel that unmoderated lists have a much lower ratio of signal to noise, meaning that they are not valuable or are full of irrelevant clutter. Whether a list is moderated or unmoderated, it is the list members and the list manager who give it value.

Thread

A thread is simply a discussion topic. There may be many discussion topics going on at once on a list, and the threads are identified in the subject header of the message. Having names for threads helps keep the list organized and helps list members read only those discussions that interest them. If you are posting to a list, be sure to include the thread name that you are posting about.

Digest

Most discussion lists are organized and distributed by E-Mail in two formats: Digest or Individual Post. A Digest format means that you will receive one large message once each day with a compilation of that days postings. It may include one post. It may include fifteen posts. It will depend on how active the list was that day.

Individual Post mode means that you will receive each post individually as it is distributed to the list. There are advantages and disadvantages to each mode.

You may want to first try the Individual Post mode on any list, especially if you belong to one of those subscription services like AOL which converts messages over 20K in size into files. That can be really annoying. You may find that an Individual Post format will allow you to preview the subject headings for posts that interest you and allows you to file, delete or read as you choose. An individual post is much easier to manage than a digest. But the choice is yours.

Sold your E-Mail address?

If you post to a discussion list and immediately or thereafter you begin to receive unsolicited E-Mail advertisements, do NOT automatically assume that it is from the discussion list and do NOT write to the list owner accusing them of selling your address to a bulk E-Mail company. I cannot speak for all list owners and moderators, but most do not and never will reveal the names or E-Mail addresses on their lists to anyone. Most moderators have their lists password-protected, which means that in order to access the list of addresses you must know the password. Some will change their passwords each week and make it random with letters and numbers.

Understand that bulk E-Mail companies can suck up your E-Mail address from just about anywhere on the Net. Do you have a Web site? Do you participate in UseNet Newsgroups? Do you participate in other discussion lists? Do you ever send anyone an E-Mail message? They can get your address from anywhere, so don't automatically lay blame to the list owner.

So, should you NOT participate in a discussion for fear of being added to bulk E-Mail lists? You should definitely participate and not be worried about it at all. Bulk E-Mail is going to be around for a while. If you like it, then read it. If you don't like it, then delete it or filter it out. It should in no way affect your decision to benefit from a discussion list by participating.

Types of Mailing List Software

There are three types of mailing list software in wide use today: Listserv, Listproc and Majordomo. All operate and maintain lists of subscribers and forward all mail received to all subscribers.

Basic Commands for Three Types of Mailing List Software Commands such as "subscribe," "unsubscribe," or "review" are sent directly to the list server. Usually that address begins: "listserv," "majordomo," or "listname-request" @domainname. Some basic commands and the syntax required by different software systems are shown below.

Messages for distribution to the subscribers must sent to an entirely different address. Usually that address begins: "listname" @domainname.

When you subscribe to a discussion group it will automatically send you basic information about the group, including how to post messages and how to unsubscribe. It is a good idea to save that message.

Many mailing lists are very particular about the address you use for sending commands or posting messages. Be sure to subscribe to a discussion group from the same e-mail address you plan to use for receiving and posting messages or your messages may be refused. Consider un-subscribing and then re-subscribing if you change e-mail addresses.
