Stay on topic. This is a list to discuss aspects of the SCA, medieval history, and Atlantian topics. It is not a place for virus warnings or the latest modern political jokes. Change your subject line. If your reply drifts the discussion from the original topic, change the subject line to reflect that.
Many people delete mail un-read based on the subject line.
Post items of general interest to the list. Send personal notes to the person. Make sure your message is addressed ONLY to the list. Unfortunately it is. The reply feature makes angry posts easy to send.
