MessageHi Tim/Flor,
A grade 2 braille test wouldn't work anyway. Since the rules and translation
tables
are readily available, the spammers would develop back-translators
in a couple of days.

Hi Flor,
Nice idea, but using braille asumes you have a braille display, and as we all
know, they are prohibitively expensive for most people.

Thankfully, JAWS also has braille drivers - indeed, one of the principal
improvements in JAWS7 was to make it possible, for the first time, I believe,
for a deaf-blind person to run their computer using Windows totally without
speech. And there's even a free, open-source braille program being developed.
(I came across that by accident last week. Anybody interested in more on
that?)
I have sometimes thought that perhaps some use of Grade 2 braille as a
little-known alternative to CAPTCHA could be devised somehow, say, for the
deaf-blind and those of us who know contracted braille. (A similar scheme for
other languages, of course, where applicable.) Folk like yahoo, Microsoft,
etc. - you've got to give them an alternative because they didn't always use
CAPTCHA, to counteract the spam-bots. I don't like CAPTCHA, but it's a big
pain we have to live with at present.

Hi Tony,
You know I was always brought up to understand that it is a noble and a good
thing for one to apologise.
I must apologise myself if I took you up wrongly in your opinion but maybe
early Mondays maybe are not such a great ideas for sending such emails!!
Now I usually read over very carefully a couple of times articles I come
across that I think would be of interest to fellow listers.
I do thankfully work and am fairly busy otherwise. It does take up an amount
of my spare time collating such articles; it is not done willy-nilly I
assure you!
I sent the article on Captchas more for ideas from people, to see what they
thought! Perhaps I should have mentioned that in a forwarding note!
Let people have a reasoned debate on issues!
Captchas did apparently assist that man in that article!
I am not saying whether I am in favour of them or not!
I will need to hear and read more on the matter from professionals in the
area like yourself and others.
Is there a policy from Vics on Captchas?
In the access for all you mentioned, for example I am using a computer with
speech. Now Jaws would be of no use to a deaf-blind person; Don't know how
a person with no arms could use a computer, but I'm sure it is possible!
You know if we all were to wait to have access for all ideally, no disabled
group would get very far on in a lifetime.
I emphasize I am in favour of access for all!
Now could we all have a reasoned debate on the matter?
Perhaps I might even be educated!
Anyway normal transmission should resume!
All the best,
Tony Sweeney.
