Misleading fault indications [RE-wrenches]

[Mark Frye]

Matt/Wrenches,

I regret and apologize for sending the post regarding having manufactures on
the list serve.  I should have directed my comments off-list to Michael
Welch.

I most certainly appreciate the input we receive from the manufactures.
Their willingness to come on-list and provide honest answers to questions
about their products is commendable.

Well, because they actually /make /what others sell, they know the 
functionality of their products better than anyone else and without them 
we would be just making guesses about a lot of different things that we 
actually don't understand at the same depth?

Consider the contributions of J. Berdner, for instance.
