I'm out and on phone. Haven't read all you wrote but was wondering about Restricted Shares. 12 months always? Or can there be agreement for less, like 6 months? Just wondering. It's just strange to me. Some 400,000,000 shares traded recently and it went down not up. Why? Why are so many leaving now when they could have at a higher pps not too long ago?
