RE: Dividends on Prefferedmouserman, I think you are only partly correct regarding perception that dividend may disappear. The other critical factor is that the Series 1 and Series 2 preferreds have poisonous conversion terms to be forced to convert to common shares. It almost looks like Series 3 and Series 5 are trading in parallel on that, but as I read prospectus Series 3 and 5 cannot be converted to common under same terms.
At this point I agree anyone buying Series 3 and 5 has to consider that the dividend may go away, and recovery in bankruptcy would not be good. I think both of these are excellent speculations sub $5. Series 1 and Series 2 are poisonous. I would short both of those if they get back to $15.
