RE: builder's mistakes
I think that this thread has the potential to do more damage than good in what should be a private matter. Something like this should be brought out in public ONLY as a last resort if no positive resolution can be found.
Also when on a forum there is no way to determine tone, inflection, sarcasm, or true intent. To top that off you usually only get one side of the story.
The point of all of that is be careful.
