Thanks, that's Ok as a temp quick fix. but postcards still remains a 3rd level sub category Below the 2nd level - with over
11,000 listings in that 3rd level category.
look at some of the other 2nd level categories in the Collectables section - every other 2nd level category has fewer entries than postcards. If the problem is to do with having to move items- how about moving the NON postcard items (of which there are 106) to a new category called 'paper and ephemera' and renaming the original category 'Postcards'. Then the 4th and 5th level categories could move up one ( i.e Collectables: Paper and ephemera: Postcards topographical:England: Essex would become Collectables: Postcards:Topographical: England: Essex )
