CTAN has a new package: LaTeX-course
LaTeX course is a brief, Beamer-based slide presentation on LaTeX, based on the CTAN/info/german/tex-kurs by Rainer Rupprecht (1988), which I have translated to English and taken to LaTeX2e/Beamer. Additional info from the CTAN/info/lshort/german/l2kurz introduction to LaTeX by Schmidt et al. This material may be used under Gnu Copyleft.

More information is at http://tug.ctan.org/pkg/latex-course (if the package is new it may take a day for that information to appear). We are supported by the TeX Users Group http://www.tug.org .
