If you truly wish to keep this on topic, you would not respond in public to the negative comments about you and defer all comments and responses of the type to private messages.

Ron - If posters were not encouraged to post only such negative comments - as if this could pass as discussion - I would have nothing to respond to and for you to judge me amiss for?

Perhaps you could ask that posters do not post only such things and refrain from this yourself?

So, short of members-only posting, what can we do to bring peace to this place? I'd rather have another solution, but I haven't been able to think of one.

Can you think of any other suggestions?
