I don't like the thumbs - they're ugly and clunky, particularly when you try to scroll down to see who has already given thumbs.
They have no place in the cool, crisp world that is NSC Modern.
As such I'm likely to bin them off completely when I can find a more suitable replacement.
You must both be on the old layout "NSC classic" still. Most people should be on "NSC modern" which is a lot fresher. You can change with the drop down in the very bottom left.
Modern will probably become compulsory in the near future as it's a lot easier to just maintain the one layout.
