Highpockets -- are you still there checking on nvbg? Is anyone? Your report of no work address is disappointing. I thought that maybe there was still a viable biz here, but apparently not.
As for those trades: they still occur from time to time, for whatever reason. One possibility is that companies like this that disappear (essentially) still have a stock symbol some up-start may want (for a reverse merger, I think it is called). So there may be some speculators out there accumulating for the future.
