Edit messages to which you are replying to a sensible minimum, just sufficient to preserve the context is the ideal. On the other hand messages that give no indication of the context may be difficult to understand. Appending a signature is useful as headers may not include your full name. File attachments, such as pictures, should not be sent to the list but should be offered for direct e-mail on request or, better, posted to the list files area on the group site where they can be retrieved by those interested. When posting files please include a meaningful description as your file name itself may not mean much to other members.
Many members have compatibility problems if mail is sent in formats other than plain text.
List members are requested to be considerate and to ensure that their mailing software is set to post messages in plain text only. Microsoft Outlook Express is a particular culprit here as it defaults to sending in html format. If you wish to continue a discussion that has wandered off topic, or is likely to be of interest to one user only, please e-mail them directly rather than through the whole List. List members experiencing problems posting to and receiving messages from the List can request the assistance of the List Manager by e-mailing details of your difficulties to Keith For further information, please check the list website.
