Rolling C this is the first incoming !, i asked "are our ego,s getting to big that we cant answer a question.........."
What i did not like was that some of the posts where critical of some one who clearly wanted to further his/her undestanding of a subject and who better to ask than an instructor? .
It would seem some did not like this on this forum a point that i disagree with.
As instructors we should all be willing to answer questions from students what ever forum we find them.
Finaly thanks to john f for an a post far more eliquent that i could have made.
