I think they are becoming easier? Or perhaps the answers are available on the internet.
I'm pleased in more than one sense that I can now scan and e-mail my crossword, because with a closing date of Monday I don't think even 1st class post would make it in time. And I haven't bought 2nd class stamps for ages; I wonder if Royal Mail are noticing a difference? I alone do 3 Telegraph puzzles per week, so multiply that by 52 weeks + 12 Brain Games, and then by the number of other people also scanning, at 50 or 60 pence a shot it must amount to a lot of lost revenue.
