I maintain a LaTeX package (mandi) but please don't hold that against me; I know it sucks. It's currently being heavily rewritten and reorganized. I am a LaTeX evangelist and am looking to mainstream LaTeX in college physics courses, both for improving written communication and for introducing students and faculty to computation. I would like to write a book on LaTeX3 programming for physics students. I am a member, and Fellow, of the American Association of Physics Teachers. I finally just joined TUG, and I think I should get reputation points for that!
