It may develop this thread further to outline a specific case... peepo.com is reasonably accessible say ~A. it more or less passes the w3c validator, and has been hand checked to some extent. it now links to a number of radio stations. these mostly work in ie6, however very few work with ie5.2 on the mac. the people who set up the radio stations have relatively sophisticated and lengthy scripts for sending users to the correct stream. I've had to shortcut this, because they ask too many questions, for our users. I don't wish to copy, let alone understand these huge tracts, neither do I wish to reverse engineer them, there might even be legal implications. Given the diversity of sites that we link to, a monolithic script for the site would be truly gargantuan. However many of the links will be down for reasons outlined above, for many users, and this makes it in my mind a very poor example, and yet there is no immediate solution that presents itself. Hopefully this explains the area which may need further development. jonathan ----- Original Message ----- From: "Charles McCathieNevile" <charles@w3.org> To: "WAI IG" <w3c-wai-ig@w3.org>; "Jonathan Chetwynd" <j.chetwynd@btinternet.com> Sent: Tuesday, September 17, 2002 12:13 PM Subject: Not making links... > > Provision of a text version and a visually interesting version of something > are two important parts of accessibility.
