I customised my rc.custom file and my rc.local.s10 fiel so that in the subject line, the name of mys list appears in all messages. Unfortunately, the subject line is duplicated every time the person who first originated a thread gets an answer. To explain more clearly, when someone answers to a message, all members of the list get the message with the correct subjetc line (like thise [List name] Subject), but the orginator of the message, gets the subject quoted twice like this : [List name] Re: [List name]: subject.
