I would like to make a few additional observations since this thread has outlasted the original posting.
I personally do not mind being corrected if I have made a mistake. To take offense would mean not learning something new. Further, when I do offer a correction it is done in good faith and is not a gotcha.
For those who do bristle when this happens then you have the option of not posting to a public forum.
With all the information available on the web it is relatively easy to check what you wish to post.
APUG would be very dull if everyone always stayed on topic.
