"To maintain consistency across Wikia, however, we will not be allowing this change in wiki custom CSS." ...makes me think of another quote... "A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines." - Ralph Waldo Emerson

This implementation is almost useless since the problem is that inexperienced users will continue to create non-existent categories that will never show up as red links because they are too new to know how to customize their CSS to make the red links show up.

Baby steps, I guess.
