As of the last report in Sept of 2007, the float was 7,617,340 but the O/S was only in the 25 million range. As you can see by the earlier post, the O/S is now almost 70 million but I'm not sure if it's insider's holding the add'l shares or if the company has increased the float.
IMO, the company is using the stock to secure new financing. That's just what I think so don't base your decision to buy on it.
