Here is an email: Dear Everyone: As some of you might have heard, I gave my one-week notification last Friday, my last day with Enron will be Thursday, 1/31. The reason of my leaving is purely visa status, I have nothing but joy working with you all in the last one and half years, the wonderful experience made the departure a painful decision. I shall be around in the next few days should you need anything from me. I'd like to thank you all for making my work at Enron such a thrill experience, for your support and friendship, I hope I will have a chance and honor to work with you again in the future. Good luck to all of us! - Zhiyun
