I agree with most of the poster's remarks you cited. Although I have received overall excellent assistance when, as a newbie, I asked questions or started a thread even after searching, quite often I have received and noticed quite brusque remarks that were not appropriate. Some people, more than others, seem to give themselves permission to snap remarks when they feel empowered. I never said anything because I just wanted to adapt to the new environment. But this is a great place to be and I do feel welcomed.
