The reason some communcation should have been issued is because if you go to almost any financial website and look at PTSC's news, it lists the Paulson PR about PTSC's participation at the Westerguard Conference.  It's not like this info was only listed on the Paulson site, or the Westerguard Conference site.  It was widely disseminated so an expectation about PTSC was created and due to something PTSC did, ie. agree to participate.  Since they cancelled out, they should have either requested/required an updated PR from Paulson to be issued indicating their absence from the roste of companies, OR, they could have simply tacked it on to the webcast cancellation PR they issued last Tuesday.  They could have simply listed it on their website.  Causing expectation from investors/potential investors and then not living up to that creation and with no explanation is more than likely going to hurt the company, not help it.  If that's the case, PTSC should be more careful not to hurt the company.  That's all.
