I still don't really believe the O/S is just over 4 mil. In the intro message the O/S is listed at 2,125,672,976 as of May 27, 2010. I'd say some dilution was thrown in there after, maybe raising the O/S to between 3 and 4 billion before the reverse split. I'd say the O/S is around 30 to 40 mil based on this, but you are right, the large volume is very interesting to say the least
