A Word about Comments

I've deleted a couple of comments in the past few days. Let me just state a few ground rules:  generally, I let comments stand. I won't delete them simply because I disagree with them or because they are critical of me. I will delete them if they use profanity, if they are spam or intended only to promote someone's commercial enterprise, or if they contain personal attacks on individuals or could be considered defamatory. I also reserve the right to come up with additional grounds for deletion, in my discretion, as the need arises. Just so ya know.
