As a 'naif ' myself , I feel that this persons posts may have intimidated contributors from either seeking or posting answers .It is sad that this debate has supplanted the purpose of this site- namely a forum where assistance may be sought and given with generosity . This person is 72 and boasts of his superior knowledge and brain power.Well hurrah for him . This forum has seen the very best of human generosity which seems to have been forgotten .Might I suggest that this person should gravitate to a site more suited to his obviously superior talents and leave the rest of us poor mortals to muck out .
