I would call if I were that close for sure. What they tell you could be very 'telling'. Although it would be limited but at least there is some 'evidence' so to speak.
Give it a try see what they say.
By the way when you call, the 'investor relations' ext. just goes to nowhere. But if you try 972-248-2244 x106 it goes to Steve's v-mail. No idea whether or not he'll pick up or call you back. I'm still waiting.
