`  == Restructuring article ==  The current article is written in classical historic fashion of ``Bible``, ``Rabbinic literature`` and ``Modern Judaism``. The result is that the Orthodox laws of Niddah are more or less arbitrarily divided between the latter two categories. There are still traces of a divide between ``Orthodox Judaism`` and ``Progressive Judaism``: in this area Conservative Judaism is distinctly different from both in theory (although less so in practice).   My suggestion would be to restructure the article by beginning with the Biblical rules, outline the role of the Talmud and classical commentaries, then outline the classical rules in one place, then discuss contemporary Orthodox practices, then outline the Conservative movement's views, then Reform etc. Will await comments before any attempt at rearrangement.
