For extra usefulness I guess the quiz should give extra marks for 
allowing different letter to number substitution schemes... I don't 
know of anyone in the UK that does the "what fun and memorable phrase 
can I tell people to use for my phone number" "1-800-SUETHEM" thing*, 
but mobile phone penetration has reached the point where the majority 
of people probably use T9**.

* Off topic, but I've occasionally wondered why it has never caught on 
in the UK.
** I've just had a sudden doubt that T9 has a standardised number to 
letter map...
