I don't have time to look well into the topic in the coming couple of days due to exam week. I'll take a look at LuxCommander's big chunk of text above when I'm done with all university stuff, and see if I have anything to add to the subject. :)
I'm not an encyclopedia with tons of information available right off the bat. I usually take a couple of hours to research a topic (like I did with that previous post), so it takes quite a lot of time.
