Hi Shawn,

Ref: <http://www.w3.org/WAI/EO/Drafts/PWD-Use-Web/2009/scenarios>

Thank you for your comments. They have been addressed as per below:

Changed to "he has reduced vision ..." to better match.

Changed to "enlarging the entire web page *on his browser* distorts the 
images" to better qualify the issue.

Changed to "Unfortunately, Mr. Yunus discovered that many websites are 
not designed to support text enlarging. For instance, sometimes the text 
can not be resized or the text on the web pages starts to overlap each 
other as he increases the text size" to address the issues.

The full text says:

Another barrier that he encounters are CAPTCHA images that he finds on 
several social networking websites. These distorted images of text are 
intended to tell computers and humans apart but Mr. Yunus can not read 
the small and distorted text, even if he enlarges the image.

I'm not sure if this is the correct document to say more. Do you have 
specific suggestions without making the text much longer?

Changed to "Only few websites provide alternatives to CAPTCHA images 
that are more accessible to him" to avoid unintentional suggestions.

This is already one of the longest scenarios. Please also see the 
rewrite a little earlier on: "For instance, sometimes the text can not 
be resized or ..." which could also include movie captions etc.

Point taken but I've changed the "accountant with blindness" scenario as 
I think that people who are deaf-blind have no other option but to learn 
braille. Also changed to "legally blind" (see more below).

Changed to "She is deaf and recently became legally blind too, but she 
can see small portions of a screen" (see more on this below too).

Added "some" to the sentence as suggested.

Changed all occurrences to "age-related".

Simplified these two sentences as suggested.

Removed this sentence as suggested.

This is intentional. Is this an issue?

Changed to "hard of hearing" to better match the description.

As per above, changed to "legally blind". I think this is quite common 
for people who are deaf-blind. Happy to discuss as needed.

Changed to "Retiree with low vision, hand termor, and memory loss".
