I see a LOT of new categories/subcategories were added last week, but Collectibles/Metalware with no subcategories is all we're going to get in Collectibles.
As for silver, copper, brass, or other metalware that doesn't qualify as an antique or collectible (the things we Yanks put on our dining room table and actually use), I think we'll have to settle for these:
Home & Garden/Dining Room/Other for metal serving dishes.
Kitchenalia/Cutlery for flatware (I learned that what we call flatware in the U.S. is called cutlery in the UK).
We'll just have to hope the potential buyers use the search box instead of looking for the categories.
