Er .... this ?
What has happened is ... at post 768 ,for some odd reason...
... probably gormlessness ... I called the next one 673 ....
... and subsequent posts got called 674, 675 etc.
... I only noticed this yesterday.
... so I've put it right.
.. but I haven't changed the "wrong-numbered ones"
... because that might muck up the " links" I sometimes put on here.
