a) if other people have done this crossword, putting its name in the title box means they can recognise it straight away (most people do that, have a look at other threads in the Crossword topic)
b) if you number the clues, we can just answer that number without having to explain "5th one" or whatever. Listing the clues underneath each other, rather than all in one paragraph, makes them easier to read this end, too :-)
