For those of you hoping that PTSC will do a reverse split and go for a new exchange listing, there is a small co. in Torrence Calif. that is trying to do it. May be worth a watch to see if they are successful.
ENOV, formerly ENVA. Listed also on London`s AIM, reverse split 1 for 45. Looking to get listed on American stock exchange. Disclosure is that I am long with it but was not happy to see the huge loss of shares. Joe
