Our List Server provides the following features:

• Lists can be completely "open" -- allowing postings by anyone on the Internet.
• Lists can be also be "public," meaning that anyone can get on the list by subscribing to it. Users can subscribe to, or unsubscribe from, a list by simply by sending the appropriate message to the list server.
• Lists can be unmoderated (any message sent to the list is immediately posted to all users on the list) or moderated (all messages are viewed by the moderator before being posted to the list).
• Postings to the list can be further controlled by use of a password or by use of a "posters list" (a list of people authorized to post to that list).
• Lists can also be private. A private list does not accept a Subscribe command; only the list administrator can add people to the list.
• Messages to a list-server mailing list can be accumulated and periodically mailed out as a digest.
• The list administrator can enter an identifying text string to appear on the Subject line of all messages (or a digest) posted to the list.
