|A mailing list is like a newsgroup,
except that articles are exchanged by email rather than as news. Often, a mailing list has
only a hundred or so members, and membership of some is restricted to those who have a
particular professional interest in the topic of the list.
Most mailing lists have two addresses: one for subscribing, unsubscribing, getting help and receiving archives, etc., and the other for actually posting and receiving messages. Because messages are exchanged by email, it is important to download mail regularly, and to unsubscribe properly, otherwise inconvenience to others can be caused by bounced email.
In Turnpike, it is possible to treat a mailing list like a newsgroup, with automatic threading and expiry of messages (see the help file or manual for notes on how to do this).
