Mailing Lists

    There are many public mailing lists out there, 90 thousand + last time I checked. In addition, there are many private lists such as our class list. In general the public lists fall into two categories, discussion lists and information lists. With the former, groups of people with like interests exchange messages. The latter are one way, much like newsletters.
Mailing lists are among the most useful tools to be found on the Net. Yes, it does take some effort to find the "right" lists. However once done you can easily and economically exchange ideas, with people all over the world. Think about it. This is no small asset.
Another virtue of mailing-lists is that they are easy to join and easy to leave. Further, the mechanism is such that a single message to a list is automatically distributed to all members of the list, be it 10 or 10,000. In addition, control commands can be sent to the mailing-list's computer to "make the elephant dance".
Of course when we talk about mailing lists, we are actually talking about server side mailing list management software (MLMs). The major MLMs programs are List Servers (listserv), Majordomo Processors (majordomo) and List Processors (listproc). Here at the school we use "listproc."
Another format for mailing lists is becoming popular, Web based. One of the more popular ones is eGroups.
Ok so how do we find that list of our dreams? Just checkout the database at Liszt.com or Tile.net or Meta-List.net. BTW did you notice that Tile.Net includes information on FTP lists, vendors and Newsgroups. Neat, isn't it? Serendipity at work! We will examine these topics shortly. In each cases, Liszt, Tile, and Meta-List you can either use a search engine or you can "browse" through the list.
At this time it is not clear if eGroup and other Web based forums are being cataloged in the same manner as the traditional lists. So it might be well directly check eGroup.
Please note that there is a distinct addressing difference when sending commands to the mailing-list's computer and when sending messages to the list's recipients.

You address the computer as:
MLMs@Domain_name
   (e.g., listproc@nova.umuc.edu), for delivery of commands. No subject and only the command (e.g., help) in the message body.

You address the list's recipients as:
list_name@Domain_name
   (e.g., capp386-l@nova.umuc.edu), for delivery of messages. Always include a subject and of course anything you wish in the message body.

Take care, you don't want to send a computer command to 10,000 list recipients. They get testy. Again, Web based forums use different rules, often requiring Web access for 'adjustments.'


An exercise for students: Find, join, and report (200 words) on a list. You distance folks send your response to our class mailing list.

An exercise for students: I do like chili. Everybody, find a Chili or is it Chile or perhaps Chilli lovers list? Send your "finds" to our mailing list. As you will note, at Sam McGee's site, there are also useful Web based forums.
