Subject: Cannot send email to Yang Zishao

 I am surprised to see that Yang Zishao posted a message here.
 I tried to send him an email, but failed. Is this a correct
 address? If Yang Zishao see this message, please check the 
 email address posted here. I think a lot of us like to know
 where you are, where you have been for all these years and
 how you are doing now.
