Just introducing myself, for the purposes of internet privacy, my name is "Quinnjin" Which is a nick name I got given as a kid... I have absolutely no credentials but an enquiring mind, I live in New Zealand, have worked all kinds of jobs, and currently work in film when I can , in trades when I have to, my hobbies include music and art, and getting in the water when I can... I'm hear to learn... I usually try searches to find answers, but of course, the deeper one gets into a subject the more obscure the questions become and the harder it is to find answers... Thank you in advance to anyone who takes the time to answer what are probably going to seem pretty basic questions... Cheers, Quinnjin.
