Gordon, this thread exemplifies everything that a welcoming community really should try to achieve. There is respect, no matter one's level of expertise. There is a sincere desire to help in a constructive manner. And for me, there is always an expectation of learning something and looking forward to seeing what others are interested in talking about. The key, I think, starts with Steve and Rose. And the unrivaled respect anyone has for them. We, at least I, would not want to say anything that would be interpreted as combative or offensive in their community. This is not the case in many photography forums. And then, it is the people who join. I can't say thank you enough.
