I just noticed a post in which Howlin says that Berg's family and friends were the investors, so it's possible that "stockholders" referred to them. In which case it wouldn't be a particularly suspicious reference.
However, since it seems from earlier threads that the company was unregistered and there aren't any records on how it was structured, what profits it made, etc., I guess this would be pretty hard to check out.
This entire e-mail is full of puzzling things.
It's unheard of for a company to actually have skilled specialists here I think this gives us an advantage, but we have to get past the "I have a friend" stage. I'm hoping a good business manager will move this along.
That's the way I read that "stockholders" remark; that may not be correct!
