Imagine reading my message, in the middle of a long thread, directed to you. What if you had made many comments, and I was responding to one of them?

I thought of that, also - impossible as the methods of quoting vary (as above). I think Michel has done a good job with it. Still, dropping a lot of the massive quoting with a 'Me too!' or a 'LOL' added to the end would be a nice goal. User training, maybe? At least we now have the option to quote or not before hitting the Reply.
