Editors here, please stop telling others to stop discussing this subject.  There was never a consensus to delete this article and there was only a very dubious consensus to merge, which was never done; the article was effectively deleted against consensus.  Several very sensible proposals for new names for this subject have been put forward which overcome the objection that an article entitled simple 'Tau' might mislead our readers into believing that there is any significant interest in the subject by serious mathematicians.  One thing is for certain, there is no clear consensus that we should have no kind if article on this subject, in fact, I am not sure that such a thing is even possible within the ethos of WP.

One way to resolve this issue is to have a civil discussion on what would be a suitable title for the subject that has been discussed at length here (I propose 'Tau (circle constant)' then start an article on the subject on that page and then start an AfD.  Alternatively we could have yet another RfC on restoring the page under a different name.
