RE: closure.....The whole US listing option for the sale of Ortsbo when it was announced and while it was being considered killed alot of momo in this stock, showed mgmts lack of judgement and quite frankly was a big FU or flipping the bird to canadian shareholders at the time of consideration of this option. Technolgy is there....mgmt. is questionable in their ability to effectively exploit the opportunities at hand...they were winning...then...the big nosedive. HAGW.
