How does one go about making a Listserv list a "digest oriented" list, in other words, how can I make Listserv accumulate mail items for one list until a sufficient number has been gathered, and then send it out in one large mail file? Are there any CMS tools that would make it easier for a list owner to moderate a "digestible list", i.e. move mail items around within his NOTEBOOK and send most or all of them out in one digest ? (Just in case we want to institute a moderator).
