I have been doing some more thinking. (It gets worse!)
I am now wondering whether in the event that a mine is added twice under different names or spellings, it would be better to leave say "B" alone, but to make a notation "See A".
Obviously, the RE would ensure that all uploads are under mine "A" , and that mine "B" is simply a redirect for the benefit of site visitors who only know the mine under name "B".
I think that this issue is worthy of some serious consideration and discussion, and that all REs should adopt the outcome as standard policy.
With respect, I suggest that we await postings of opinion on this, before the admins make a final decision.
