I am hoping to use TOPICS to set up a sublist on my list for book discussion. According to the manual, use of TOPICS is recommended for an edited list (which mine is not) but as I understand it and wish to use it, this option should work for my purposes on an unedited list as well. I'd appreciate some clarification if I have misunderstood the documentation (as well as pointers in a more appropriate direction if there is one) but if a message correctly has the name of the TOPIC as the first text after the colon in the SUBJECT field, shouldn't only subscribers who have that particular topic as one of their subscription options receive that particular message? (In testing this I have sent mail to the entire list!) And, subscribing to a specific topic should not foreclose receiving general mail sent to the list, correct? For subscribers to the sublist: TOPICS= Books, Al l; for nonsubscribers to the sublist, once TOPICS are enabled, is it then necessary for me to add TOPICS= All for their subscriptions? Your assistance is greatly appreciated! Lett Proctor
