This is a very old chestnut ..... fiercely debated when the 'crossword' subsection was first introduced .... look back into the archives - there is a lot of history on this subject .....
It's a shambles caused by an over-zealous AbEd at the time of the change - who wouldn't listen to the almost unanimous view of the abers that a subsection was not needed .....crossword questions far outnumber the rest, yet crosswords was consigned to a subsection ....
This is also linked to the old debate as to whether the heading (e.g. Quizzes and Puzzles) should be just that, a heading.
Existing abers at the time of change largely voted not to use the subsection 'crossword' ---
