@Freightman - I'm not worried about it. This is a public online forum. If I needed to avoid negative comments, I wouldn't post. However, I want to learn, so posting (and sometimes being wrong) is part of the process. I actually appreciate when folks point out my misconceptions if they are able to back it up. I can certainly preface my comments more frequently, but that will not prevent some folks on a forum from needling (note that the post which you are referencing was made because the member knew I was new to the game).
