Class chain emails have a long history on the net. See: http://urbanlegends.about.com/library/blclass.htm http://hoaxinfo.com/newcastle.html http://www.ednet.ns.ca/educ/schoolpages/millcove/project.html The irony is that this almost always shuts down the school's mail servers, and yet there are more such projects each year. On one hand, I am glad that teachers are trying to find news ways of engaging their students. On the other, that so few teachers recognize the geometric possibilities may be a good gauge of "network illiteracy." Alex Halavais
