Well I never heard of insider buying as anything but good and I've never seen such consistant buying by an insider before in my life..I'm sure Sheldon is buying for one reason only and it has nothing to do with us. And despite what anyone says here Sheldon knows a lot more then we do about the situation of this company and he's buying. So follow the money.
On another note when, if ever, will we get some idea of what happened at the GSF? I sure am courious. I've searched for some results but can find absolutely nothing worth talking about
