Most brokers will buy and sell it, in fact I only know of two that wont. It being a shell is a non issue for trading. The reason some cant\wont trade it is there is a DTC chill on the stock, that being said it is not a global chill so again most brokers wont will trade it.
If it is a shell or not has no bearing on trading only on depositing of certificates and the rule 144 holding period.
Lastly, the S1 is for SEC fully reporting companies and not a mandatory filing. This is a voluntary un-audited pink reporter and doing such it remains at the top tier of the pink sheets.
I buy and sell it without a any issue as do most on this board.
It will always be a shell, unless it gets bought out but it could still apply for Nasdaq listing providing they meet the criteria as far as stock price assets etc...
DTC chill still in effect after it was promised to be lifted... I don't understand some of the hoopla here because frankly if this stock was going anywhere you would be putting more and more into it every 2 weeks (especially with buyout suggested.) Obviously even the large shareholders know the risks here as they aren't buying enough to prop this back to where they want it to go. Cant believe the hype.
