<p><pre><code>    The way most people keep up to date on network news is through
    subscription to a number of mail reflectors (also known as mail
    exploders).  Mail reflectors are special electronic mailboxes which,
    when they receive a message, resend it to a list of other mailboxes.
    This in effect creates a discussion group on a particular topic.
    Each subscriber sees all the mail forwarded by the reflector, and if
    one wants to put his &quot;two cents&quot; in sends a message with the comments
    to the reflector.

I wish they were still called mail exploders.
