while i believe this happens westcott, considering NSL is on the verge of making it as an iron ore producer, i don't see the directors risking 3-4 years jail time for a~ $50k profit...the last director converting was, i think ,cedric a few months ago and he is on an annual salary of about $300k or more , so no, i dont think it's them playing around with the SP today..IMO
