well, as for American Bulls--keep track of its success. To be successful in trading/investing, it helps to 1) have Level II, 2) become almost an expert in charting(ie, Clay Trader), 3) do some serious DD on stocks, such as URST.
who do you think you are that you can demand answers from everyone. everyone that is a shareholder bought because they felt the stock price would go up. what level of DD they did is up to them, if you are anyone doesn't 'feel' the same way anymore by all means sell! all the great info is public and available on their webiste and PR's...
