Many of you knew that I was having bypass surgery but others did not. I am home after a 7.5 hr. procedure to replace 5 arteries and having a better than anticipated recovery so I should be able to catch up shortly. In the meantime I wanted to thank those who have sent new contributions for posting, before and during my hospitalization and let you know how much each is appreciated, even if I have not responded. I will get them all posted shortly and urge you to continue to pass along new data. Although not quite up to par, I can't tell you how thrilled I am to be back doing what I love best. Nola
