A great topic Cheryl...so many on the forum seem to have forgotten the rules for the forum, and common courtesy in interpersonal communication.
I can agree to disagree with the best of us, and sometimes the need to be right for others makes the forum too devisive to be an effective tool for sharing best practices and information.
If members feel the need to rant, it is a better choice to type their frustrations out to externalize their feelings, and then delete their message before posting. You still have the therapeutic benefits without all of the resulting turbulence.
A nebulous caste system does not exist on an open forum...J/S
