I can see how the truley dim-witted might forget that other countries
have phone numbers with differing lengths and formatting/punctuation,
but there are tons of sites where it takes multiple tries when
entering even a bog-standard USA 10-0digit phone nubmer because they
are completely flummuxed by an area code in parens or hyphens in the
usual places (or lack of hyhpens in the usual places). This stuff
isn't that hard, people...

Indeed. There is a tiny but brightly burning kernel of hate in my
heart for web sites (and their developers) that refuse to accept
credit card numbers entered with spaces _as_they_are_shown_on_the_card_!

I've concluded that using PHP causes debilitating and irreversible
brain damage.
