Postings are automatically numbered when you specify "Separate" notebooks because a unique fileid has to be generated, but apart from that LISTSERV does not internally number its postings. What you see in LDBASE is just the index of the posting among the ones presently available; remove one of the LOG files and the ID's get scaled down. There is presently no way to assign "article numbers" or the like, but if the list is moderated it is of course a trivial task for you to write an XEDIT macro that will insert a unique number on top of the message body.
