If your response to a message will only be of interest to the author of the original message, reply by direct E-mail. Do not send the message to all participants. Identify yourself with a signature block, but limit it to four lines. Most E-mail software allows you to set up a signature that is automatically added to all outgoing messages. Do NOT use solid capital letters.
Internet users interpret that as shouting.
Top of this Page 2. Mailing Lists Internet mailing lists consist of discussions carried on by E-mail in view of all subscribers to the list. Software at the server hosting the list handles subscriptions and distribution of messages automatically. Some lists have a moderator who screens all messages before they are distributed. All lists have one or more owners who may remove subscribers who do not adhere to the protocol for that list.
