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.
