Very important IMO.
I don't agree or disagree with the subject or conversation, but want to make a point. This is “exactly” the sort of stuff we need on these boards. If someone makes a statement, rather than run the risk of a del, simply and respectfully state why you agree or disagree with another posters POST, and we can move on. This is a very good feedback statement, and handled very professionally. This way we can show our emotions, why we feel that way, and back it up with what we have. Hopefully we can each respect the feedback, and not turn it into a board brawl.
