RE: CAPTCHA/web-security problems separated by cognitive disability?

Agree that separating out by cognitive disability is not functionally useful.. Maybe recast solely in terms of functional limitations without detailed mapping to specific cognitive disabilities.  We just need to make sure we've covered as many  "outcomes" of as many cognitive disabilities as possible in a list of functional limitations..

While your list seems complete I agree it looking very difficult to separate by cog. disability. I'm afraid I have no inspiration at this point.
