1. Talks
   (a) Crossing angle (Tauchi)

       * Several proposals for crossing angle
           head-on
           vertical crossing angle ~0.3mrad
           small angle 2mrad, 7mrad
           large angle 20mrad, 30mrad

       * merits and demerits
           head-on: beam cal. can be placed very near the IP
           small: high Lum. can be expected even without crab cavity
           large: better for beam diagnostics

       * Need to list up issues for discussing crossing angle

   (b) 2nd IP (Sugimoto)

       * Having 2 IP's is consensus among LC user community
       * 2nd IP should be compatible with gamma-gamma
       * Crossing angle is to be discussed
