Veronica,
   you should address your requests to LISTSERV AT DEARN, not to
 LSTSRV-L which is the list.
 
   I tried to answer to you directly and send you the help files, but
 I get an 'address unknown' when I type in your destination, which puzzles
 me a bit.
 
   Anyway, good luck.
 
 Alberto...
