You have been added to the TREE-RING_ISOTOPES  mailing list (trisotopes) by Steve Leavitt <sleavitt@LTRR.ARIZONA.EDU>.

Please save this message for future reference, especially if this is the first time you are subscribing to an electronic mailing list. If you ever need to leave the list, you will find the  necessary instructions below.

Perhaps  more importantly,  saving a  copy of  this message  (and of  all future subscription notices  from other mailing lists) in  a special mail folder will give you instant access to the list of mailing lists that you are subscribed  to. This may  prove very useful the  next time you  go on vacation and  need to leave  the lists temporarily so  as not to  fill up your  mailbox while  you  are away!  You should  also  save the  "welcome messages" from the  list owners that you will  occasionally receive after subscribing to a new list.


To send a message to all the people currently subscribed to the list, just send mail to TREE-RING_ISOTOPES@LISTSERV.ARIZONA.EDU. This is called "sending mail to the list," because you send mail to a single address and LISTSERV  makes copies  for  all  the people  who  have subscribed.  This address (TREE-RING_ISOTOPES@LISTSERV.ARIZONA.EDU)  is  also  called  the "list address." You must never try to send any  command to that address, as it  would be distributed  to all the  people who have  subscribed. All commands must be sent to the "LISTSERV address," LISTSERV@LISTSERV.ARIZONA.EDU.  It is very important to understand  the difference between  the two, but  fortunately it is not  complicated. The LISTSERV address is like a FAX number that  connects you to  a machine, whereas the list address is like a  normal voice line connecting you to a person. If you make a mistake and dial the FAX number when you wanted to talk to someone on the phone, you will quickly realize that you used the wrong number and call again. No harm will have been done. If on the other hand you accidentally make your FAX call someone's voice line, the person receiving the call will be inconvenienced, especially if your FAX then re-dials every 5  minutes. The fact that most people will eventually connect the FAX machine to the voice  line to allow the FAX to go through and make the  calls stop does not  mean that you should  continue to send FAXes to  the voice number.  People would just get mad at you.  It works pretty much the same way with mailing lists, with the difference that you are  calling hundreds  or  thousands  of people  at  the  same time,  and consequently  you  can  expect a  lot  of  people  to  get upset  if  you consistently send commands to the list address.


You   may leave the list at any time by sending a "SIGNOFF TREE-RING_ISOTOPES"  command  to LISTSERV@LISTSERV.ARIZONA.EDU.  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

TREE-RING_ISOTOPES 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  TREE-RING_ISOTOPES. If you send a "SET TREE-RING_ISOTOPES 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 TREE-RING_ISOTOPES NOACK NOREPRO".


Following instructions from  the list  owner, your  subscription options have been  set to "REPRO"  rather than  the usual LISTSERV  defaults. For more   information   about subscription options, send a "QUERY TREE-RING_ISOTOPES" command to LISTSERV@LISTSERV.ARIZONA.EDU.


Contributions sent to this list are automatically archived. You can get a list of the available archive files by sending an "INDEX TREE-RING_ISOTOPES"  command  to LISTSERV@LISTSERV.ARIZONA.EDU.  You  can then order these  files with a "GET  TREE-RING_ISOTOPES LOGxxxx" command, or using LISTSERV's  database search facilities. Send an "INFO DATABASE" command for more information on the latter.


This  list is  available  in digest  form.  If you wish to receive  the digested version  of the  postings, just  issue a  SET TREE-RING_ISOTOPES DIGEST command.


IMPORTANT: This list is confidential. You should not publicly mention its existence, or forward copies of information you have obtained from it to third  parties. Please  note that the "GIVE" command is  automatically disabled for all archive files.


Please note that  it is presently possible for other  people to determine that  you are  signed up  to the  list through  the use  of the  "REVIEW" command,  which  returns   the  e-mail  address  and  name   of  all  the subscribers. If  you do not  want your name to  be visible, just  issue a "SET TREE-RING_ISOTOPES CONCEAL" command.


More  information on LISTSERV commands can be found  in the  LISTSERV reference  card, which  you can  retrieve  by sending  an "INFO  REFCARD" command to LISTSERV@LISTSERV.ARIZONA.EDU.
