That's what I thought when I first saw it @ $0.0030 about an hour ago, and then they moved it up to $0.0293 (or thereabouts) - but it's been @ $0.0031 too long to be a typo, and the bid is currently 0.0300 by RAFF, and NITE would have noticed they weren't trading shares @ 0.031 by now, and that's too many typos - they would be careful after the first typo.
Seems to me the weight of the evidence comes down on the side of it being a signal.
