Manufactures on the list [RE-wrenches]

[Blair May]

Mark , Their value to us (the manufactures) here on the wrench list is
quite high. Yes there are some manufactures that DO seem to pontificate
w/out the chastising from Michael, while others offer their comments in
a rather concise manner. Sounds like life in general. With that being
said, I would like to say THANKS to ALL the reps that do take the time
to watch the list & comment when they can. THANKS

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.
