I'd like to add to Jim's advice.  As I understand it, the procedure he
described will enable him to authorize someone else to update certain
files that already exist, but would not enable them to create new files.
That can only be done by altering the FILELIST, and the FILELIST can only
be altered by a listowner.  A simpler method would be to add the other
person as an owner for that list.  (The disadvantage is that they then
share with you complete authority over all aspects of your list, so you
will be subject to any mistakes that they might make.)
 
You can send GET <listname> LIST (HEADER NOL PW=XXXXXXXX
to LISTSERV.  Then add the line *  Owner= my.friends@address
after the original Owner line that contains your address (taking care to
see that the "*" is in column 1, and that a blank follows "=").  Also,
edit the file so the first line reads PUT <listname> LIST PW=XXXXXXXX .
Then send it back to the LISTSERV and you're done.  Thereafter your friend
can add files, revise and/or delete them (and do any other list-owner
function) just as you can, with the use of the list's password just as you
use it.
 
I hope you also know some basic rules of LISTSERV file management, such as
you need to add a new file's name to the FILELIST *before* you can PUT the
new file to the LISTSERV, and you need to delete a file's name from
FILELIST *after* you have deleted a file, otherwise your attempt to PUT the
FILELIST will be rejected.
 
I'm actually not much more than a novice at this, so please everyone,
correct me if I'm wrong.
