STAR Correlations and Fluctuations PWG

[Xiaofeng Luo <xfluo.star AT hotmail.com>]

Hi Grigory,

    Thank you for addressing comments from Hanna and Takafumi.
     I have no more comments and sign off, enjoy the conference !

     Please send slides in PWG earlier next time. Thanks.

Best Regards,
Xiaofeng
