Yazie has a much bigger audience, doesn't he.
He can put out a PR saying anything he needs to say.
He does not need others to speak for him.
As a CEO, I would think he would be uncomfortable with anyone speaking for him, if he/she was not authorized.
BUT YES, he CAN post on this board. NOTHING is stopping him.
In fact, I believe he has, not 100%. But not the point. HE CAN.
