I'm a relative newcomer - I take it that if you want on a list, you send a freepmail to the keeper of the list? Thanks.
That's correct. Also - Some of the topics have more than one name listed after them as well, so they may each have different lists for that topic, or there may be just one "keeper" and everyone else pings the same list. You can always ask by freepmail if their lists are the same as the others. :)
