Information I received suggests that only MM's can Short a pink sheet. Please correct me if I'm wrong on that. However having just come out of another stock debacle THR*. People there voicing caution where called all sorts of things, by myself included. All the DD I performed looked good and solid. However they turned out to be correct. I am NOT stating that I think Pihn will crash. All DD I can see on this one suggests GOOD THINGS AHEAD. However, substantiated voices of caution are as needed as substantiated voices of encouragement.
