There may well be many more class files out there than are currently available on CTAN. For instance, nyj.cls, the class for the New York Journal of Mathematics, has never been posted to CTAN (but will be, shortly). I suggest some kind of call for submissions to the contrib/supported section of CTAN's latex section. I suspect there would be a great many of them. It might make sense to include these classes as an official part of latex, so the commercial distributions will include them as well. --Mark -------------------------------------------------------------------------- Mark Steinberger | http://math.albany.edu:8800/~mark Dept. of Math. & Stat | SUNY at Albany | Albany, NY 12222 | Editor in Chief, New York Journal of Mathematics [log in to unmask] | http://nyjm.albany.edu:8000/nyjm.html --------------------------------------------------------------------------
