"I'll say it again, because apparently you are not listening: The unsecured loan by PTSC to TPL was IMO a blunder. It should have been secured. A mere "Promisary Note" is something that should be used to assist a family member or such (in situations where you have faith that the person/entity will pay you back), not in a business situation."

This is a fail! A 'blunder' would be more like not securing the first loan, and then after realizing the situation, making sure the second loan was secured. This is backwards, and I want to know why.
