(FORTUNE Magazine) – I find it hard to understand why I am deeply embroiled in a chain letter. I received it a month ago and never for a moment did I consider not doing as it said, perhaps because it was my first one . . . The chain letter I received has a gimmick. It is a feminist chain letter. It says that it was started in Nashville by a woman who needed ''investment capital,'' and that it should only be sent from one woman to another . . . -- From an article by Anna Quindlen in the New York Times.
