You are posting on the list ok.

If you are concerned because you don't see your message on the list, here is a excerpt from the message you got when you signed onto the list.

As I had the same problem.

You may leave the list at any time by sending a "SIGNOFF PICLIST" command
to LISTSERV@MITVMA.MIT.EDU (or LISTSERV@MITVMA.BITNET). You can also tell
LISTSERV how you want  it to confirm the receipt of  messages you send to
the list.  If you  do not trust  the system, send  a "SET  PICLIST REPRO"
command and LISTSERV will  send you a copy of your  own messages, so that
you can see that  the message was distributed and did  not get damaged on
the  way. After  a while  you  may find  that this  is getting  annoying,
especially if  your mail program  does not tell  you that the  message is
from you when it  informs you that new mail has  arrived from PICLIST. If
you send  a "SET PICLIST ACK  NOREPRO" command, LISTSERV will  mail you a
short acknowledgement instead, which will  look different in your mailbox
directory. With most mail programs you will know immediately that this is
an  acknowledgement  you  can  read  later. Finally,  you  can  turn  off
acknowledgements completely with "SET PICLIST NOACK NOREPRO".
