Wall Street other than it not being verifiable and also obviously being his personal agenda, not that of the company, or the stock, there is nothing wrong with it, however since the board is monitored by the company and the accusation has strong innuendo of slander, I think it is wise to steer clear of this type material since it is more a matter for the courts.
If you, or any posters wish to find out this sort of thing PM him and get his email address I'm sure he will gladly share it.
Since it is not particularly useful to know how one poster feels toward a a company official based on his *unverifiable run ins", I suggest he merely deal with the company in general. He may chooses to call the company a POS due to lousey management, that is fine no problem here, but that is different and a more general comment and not one with slanderous implications.
