Thank you for these tutorials. I have been willing to teach LaTeX to some of my grad students friends in the biology department (these poor souls still use Microsoft Word) and your link will definitely come in handy !
Rest assured that my tutorials have been tried-and-tested by many under- and post-grads over the years. They've been included in college & university syllabi and I've get a lot of positive feedback from postgrads who've opted for the LaTeX route rather than word processors.
