Oops. Should I withdraw the PDF from the post? I feel like preparing and studying an exam for tomorrow's appointment. I need to learn enough to explain him and do a perfect explanation in the first 20 seconds to gain his attention and interest or he will refuse to listen and help. I'm having university flashbacks, I hadn't studied for ages. Gosh, and my printer run out of black ink... I hope I can buy a new cartridge tomorrow or I wil have no documents to show him.
