  1. April 3rd new postdoc from Korea, DongJo, is coming. He will be working on computing front, his expertise is in charmonium physics. April 27-28 visit from USA, Edward Kistenev of BNL and Richard Seto of Riverside California. Discussion on future PHENIX upgrade activities. Wladek will talk about T0 on April 13th 10:15 round table room. I am giving a colloquium on May 19th on RHIC high-pT physics. Friday March 31st 2006
