To all users of the Apache Point Observatory 3.5m telescope and other interested parties: We have set up a mail server and archiver for discussion of various aspects of the 3.5m telescope, patterned after the mail server for the Sloan Digital Sky Survey. Mail sent to one of the mail exploders below will be disseminated to all subscribers, and will be archived on a secure WWW site, accessible with xmosaic or Netscape. We hope that this will facilitate communication about the telescope between members at different institutions, and will also serve as an archive of useful information about the telescope. To subscribe (or unsubscribe) to any of the servers below, please send mail to Michael Strauss (strauss@astro.princeton.edu). To send a message to one of the servers, send mail to (server-name)@astro.princeton.edu. It is useful in these messages to always include a subject (as this will appear in the index of messages on the WWW archive), include the date at the top of the message, and sign your name on the bottom (last name too; we get many messages on the SDSS server signed by "Jim" or "Don", leaving us all guessing). The mail is archived at the following URL: http://astro.princeton.edu:82/mailinglists.html (accesible from the Princeton Astrophysics homepage, http://astro.princeton.edu). At the moment, access is allowed from computers in the astronomy departments at Princeton, University of Chicago (including Yerkes), Fermilab, University of New Mexico, University of Washington, Washington State, and Apache Point itself. If you are unable to access this and you think you should be able to, or if you think more locations should be added to this list, please send mail to Michael Strauss. The mailing lists we have include: apo35-general General discussions about the 3.5m; including items that will have widespread interest to people in the 3.5m community. apo35-telescope Discussions about various mechanical aspects of the telescope itself, and related structures (dome, control room, etc.) apo35-dis Discussions about the Double Imaging Spectrograph. apo35-grim Discussions about the GRism Infrared IMager. apo35-dsc Discussions about the Drift Scan Camera. apo35-hri Discussions about the High Resolution Imager. apo35-echelle Discussions about the Echelle. apo35-guider Discussions about the offset guider. apo35-chaos Discussions about Adaptive Optics at APO. apo35-computers Discussion about various computer-related issues at APO, both hardware and software. This would include discussion of the remote observer interface. More mailers can be added if the need arises; just let Michael Strauss know. There is nothing wrong with posting a message to more than one of these mailers. Although we will need to guard against frivolous messages flooding people's e-mail, we clearly need to increase the degree of communication between users of the 3.5m telescope, and our experience with SDSS has shown us that this is one effective way of doing so. Cheers, Michael
