I'm not sure what you are trying to say with your comment.
I have a Master's Degree in Education and have re-read my post. I have found no grammatical nor spelling errors. What's your point?
I don't know you, so I apologise <img src="http://www.catsailor.com/forums/images/graemlins/blush.gif" alt="" /> But I just felt that, for a High School Teacher, you were a little aggressive and intolerant. There should be more to a High School Teacher than perfect grammer and spelling. People are trying to help you.
