Hi guys, I've trimmed some of the bickering from this thread. As it stands now, its not a bad one, and I hope we can all move forward.
froggarana:, I hate to be unwelcoming, but I want to go on record as saying, you arrived with an attitude, and I want to ask you to drop it. You bought a textbook. Many people do that. You have O-levels. Many people have that. That doesn't make anything about you, your thoughts, or your posts better, or worse, or better because they're worse, or better because they're harder won, or whatever.
Something may be poorly explained across the books and these posts. We can work with our posts. You wanna write a letter to the authors of the books, go ahead. More than that, its out of our scope.
