i wanna send an email to the person who made these tutorials but i cannot find his/her email.

What do you want to mail him about? I think in the past, the best way to reach Jeff (NeHe) is to post on the forum...

he has said in his tutorials to email him abouttthings i just cant find his email, a certain topic and a question about background bitmaps

As far as I know Jeff is still very busy, like we all are, so why don't you just ask the question here?
