From the S8 filed recently:
We are authorized to issue 900,000,000 shares of Common stock, $0.001 par value. As of the date of this registration statement, we had 194,273,335 Common Shares issued and outstanding.
194 +200 =394 million outstanding
Add ?? for stock issued to pay debt, salaries, etc
My guess is they have about 500 million OS
JMO
PS: as of 12/20/10 when they filed the original S8 they had 68.5 million OS. The 194 million OS is as of 2/21/11; therefore they issued approx 126 million share in about 2 months
I might have to ammend my estimate to say 600 million by the time the file the 10K for 2010
