Whilst using tinyurl is justifiable where the URL in question is likely
of ephemeral interest (and especially if it's huge), for a post like this
that could usefully be found by someone DejaGoogling years hence, it's
better to provide the real URL, no matter how convoluted that might be.

Remember that all these "make a short URL" services only work for a few
weeks, not in perpetuity. (Or perhaps you didn't know that?)

Besides, Peter's original URL is hardly overtaxing; it even fits on one
line:

http://www.wppltd.demon.co.uk/WPP/Wiring/UK_telephone/uk_telephone.html

Brian,

Point taken, It just looked long in the address bar!

However tinyurl's addresses do not expire...ever!

(From their home page)
"Are you sick of posting URLs in emails only to have it break when sent
causing the recipient to have to cut and paste it back together? Then you've
come to the right place. By entering in a URL in the text field below, we
will create a tiny URL that will not break in email postings and never
expires."

Sparks...
