None of that has anything to do with anything I have said of course.
Just another of your typical tactics of misdirection Erik.

Somewhere along the line I stated that I agreed with you on that.

That you can't tell seems to be a recurring problem for you whenever I post.
One might think it is intentional.

Nope.
I said the elevator would still level with the floor successfully because of
the way the elevator control systems operate.

Nope.
I was pointing you towards the section on how the control system operates.

Thats a disingenuous exagerration on your part. You know exactly what I
meant by what I said.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Pretty much what I said in the last post. The biggest difference between us
is that you seem to take all this discussion very very seriously as if your
self esteem was at stake. I suppose thats why you seem to want to turn
various discussions into "one-ups-manship" pissing matches.
What seems silly about it is that from where I sit you seem to be held in
fairly high regard by most people here including me.
I have a hard time understanding why you go way out of your way to alienate
others in a forum devoted mainly to friendly discussion as opposed to formal
scientific discussion.

You make this kind of threat regularly enough. Don't you get tired of the
sophomore debate team?
Talking to anyone on a mailing list is optional. No one is holding a *pun*
to your head.
