The only problem I have had with it is how vague the information is. Other issues would be posters posting E-mail replies from the company. That could be insider information or down right illegal to do. Is it? I hate those because there is no link so it is obviously near i.possible to validate. I know as a manager of a multimillion dollar division of a company that I would not want my E-Mails shared on a Yahoo MB.
That is the short of it. I have shares and it would be funny to me if they made me some money.
