There was a "plea for help" in the mailserver of LXF151.
Check out "The Grace App" iPad type picture exchange application for non-verbal people.
From my reading of the letter, what the person is looking for is a picture exchange application, which can be used for autistic people and other speech impaired people.
I know nothing about these things other than that they exist.
A colleague has an autistic child.

Hope you can pass this info on and hopefully others may be able to chime in.
Mods/Admins: This is a great cause, anyway you could make this a sticky or move it to a really active spot, just for a little while???
