I actually agree with you Lu, but surely if we at-least start off with this sort of clear "statement of intent" the thread has a fighting chance of initially heading in the direction that the original poster might have hoped or needed. If the rest of us elect to then diverge into all sorts of fascinating technical discussion subsequently (and lets face it, we usually do) that surely doesn't negate the usefulness of a reasonably clear steer at the start from the questioner.
