Instructors, students, know it all, experts and the guy you can ask anything, BUT you can't tell him nothing. We all come in contact with all kinds. Some that call them self, instructor, that don't have a clue how to teach. Some that call them self, students, that will not learn. Each of you have done a good job pointing out many things. It is good to have a site like this that does give a new comer a fighting chance. Thank goodness the beat goes on.
