I am not worried about SP and PTK technology, but have concern.There is a great difference between worry and concern. A worried person sees a problem, and a concerned person solves a problem. My concern been always the behaviour of managmets and them not concern about retial shareholders. What is the big secret they hiding from us! is 6 years of waitting is not enough. There word about(we care for loyal Shareholders) Is not valid to me any more. Action is lauder than cheap promises.So far a lot of promises but no action. the way I look at it that either managment is hiding big secret posative or negative from us or they are not telling truth ,both is ilegal to me.
