Announcements
*) A mailing list for the CDC subgroup is now available:
      jlccdc@jlcux1.kek.jp
   to which you can send an e-mail, if you want to distribute
   it to all the subgroup members.
   K.Norik was added to the list.

*) T.Abe showed his transpearencies used in the 50th JPS meeting.
   The transpearencies summarize the recent progress of the JLC CDC 
   R&D including preliminary results from measurements of
   wire tension and sag (both gravitational and electrostatic).
