Thanks Octavian,
I have corrected the question, it could have certainly be written in a better
way. I was in a hurry to test it live. (English is not my native language also!)
Yes, I also don't think these types of CAPTCHA will be the right choice for
large sites where they have to change the question every now and then. But I
think it is certainly is reasonable enough for the sites which don't want to
use visual or audio CAPTCHAS.
Remember a spammer will have to target the site and CAPTCHA system + the
question specifically to break in. It means fully automated bots can not fill
your site with spams. right?
I also agree that some type of automatic question generator or random question
selector would be nice. Stuff for version 0.6!

Ok, I visited your site, but I don't think this kind of Captcha will be used
by those big sites that need to use a Captcha system.
Nobody likes to add and add new questions and remove the old questions which
are understood by spam programs.
The questions that have different numbers inside, in digits or words, can be
easily parsed and recognized by a spam program.
Other questions might be hard to understand even by a sighted. For example
here is a question I got from your site:
Type the first letters of following words "you out no".
How many letters from each word do I need to type?
I think that this might have been better written as:
Type the first letter of each of the following words: you, out, no.
English is not my native language, but I think that this way is clearer.

Hi Octavian,
I will send you the script once I have completed my final checking in few
hours time.
If you would like to see it in action, please visit nirandas.com It is my
new personal site..
The CAPTCHA is used to protect both the comments form and new registration
form.
Yes I agree that most site don't need any CAPTCHA mainly because they don't
have enough traffic to interest spammers. But it is a problem for large
sites. Also the issue of not being able to understand the language will be
there for any method of CAPTCHA although for text-based CAPTCHAS it is
certainly a larger issue. So, the site admins should ask simpler questions
which can be solved from the question itself or should target the questions
specifically towards the types of visitors the site has.

I would also like to test it.
I don't think the words captcha and accessible can go well together.
Some images generated by captcha are not very accessible even for the
sighted. They are hard to understand sometimes.
I think that the most accessible (somehow) captchas for the blind are
those
that allow downloading a sound file, but they are accessible only for the
blind persons that don't have other disabilities.
A text message could be absolutely inaccessible if the user doesn't
understand the language of that text.
Everybody knows what it means user, username, password, but it might not
understand a more complex question.
A captcha which is very simple can be bypassed by a program especially
made
for this, and if there is a limited number of question types, it could be
very easy to try them all, or skip those types which may be harder to
parse.
The truth is that most of the sites don't need a captcha at all, but many
web developers think that it is cool to add something like that to their
site.

I think the best accessible CAPTCHA would be a text-based CAPTCHA using
challenge - response method.
For last few days, I've been working on a plug-in for wordpress to
implement
a CAPTCHA of this type.
The question and the answer are set by the admin through the admin panel.
Questions like "type the word 'red' in the box" are used for validation.
Logic for these types of CAPTCHAS using question/answer model are pretty
straight forward and very platform depended.
BTW, Let me know if you would like to test it out (beta)!

Hi,
Sorry. Yes. This would be for an in-house application. No particular
content control system. I'm looking for the logic more than anything
else.
I'm sure the developers would also like to be able to see it in action.
Thanks.

Hi,
Does anyone have or can you point to the code for an accessible captia?
Thanks.
