This is the last I'll post on the matter, but on a thread a little while back, you wondered why, and lamented the fact that, knowledgeable posters like rockm and others aren't posting much, if at all on here anymore. Just so you know, in large part those folks are not posting because of posters like you (yes, I have that straight from the sources).
If you're serious about learning on here, then keep your mouth shut and respect other people's threads. If not, go find some other playground to play in.
Happy Thanksgiving everyone.
