***Stop wasting your time.*** That’s a laugh! You come on this thread, freely admit that you don’t have a clue about what’s going on, and then accuse us of wasting your time? You have 2 years of homework to do, and maybe after you complete it, you will have something useful to contribute. As it is, you need to stop now before you make a total fool of yourself for talking about a subject you know nothing about. You should be embarrassed to admit you are so uneducated.
