OK, all understood. It seems to me that no matter how the forum is organised, not everyone will agree with the organisation ("Quot homines, tot sententiae"), and so one idea that might be considered is to cross-reference key posts under alternate headings. For example, one theme that frequently recurs in discussions are the Ashoka recipes : if we stick with the current idea of partitioning them into bases, main courses, side dishes, etc., then there could also be a top-level theme (called, say, "Recipes by origin") under which there would be second-level threads called (say) "Ashoka Recipes", "Bruce Edwards' Recipes", ... which would not duplicate the existing entries but would simply containing a complete set of links to them.
Might this have merit, do you think ?
