If you don't mind receiving a suggestion from me, I'd add something: AS Mr. Orr says, perhaps the best info. available on how webmasters should make their sites accessible to all and everyone, not all are willing to change their view just because there is a "tiny community on the web who wants to be able to browse with outdated browsers" (answer I once got when asked a site to re-design to be more Opera/Arachne/Lynx compatible)
You could give it a personal touch, however, which I believe would make it nicer and more attractive for a webmaster to redesign his/her site to enable everyone... First, try it with Lynx. If you can't access the site (as I am 90% sure will hapen) you can then answer them you are blind and are thus forced to use an old "text only" browser for those kind are the only ones your text-to-speech program can read from, so "upgrading" to a graphical one would leave you unable to get anything useful from the web unless your spouse/ a friend /someone helps you at every step... You could then add that recently you were perfectly capable of reading everything at their "wonderful" (be sure to add this!!!) site, but have had a lot of troubles recently... Few WBs. can resist that.
