It seems as though every day we are being warned that once something is on the internet it never really disappears. Although I can find articles written about me 9 years ago http://www.timeshighereducation.co.uk/189972.article unfortunately I can’t find my new webpages (and nor can anyone else!) because the powers that be have changed a single character in the URL! They’ve decided that underscores are out of fashion and hyphens are the new black! So my webpage is now at http://www.ucl.ac.uk/uclic/people/a-cox. The cost of this tiny change? My business cards need re-printing, URLs on posters being displayed at CHI2013 won’t work, and my colleagues and are having to go through all our webpages updating the links.
