[Nfb-science] scoring braille input devices

[Tami Kinney]

Ah. I may be coming to you soon with many questions. /smile/

As far as popping said survey onto a website... I got mine fixed (whew) 
and can now get back to building it. I'm running it on Drupal and can 
build a survey such as John describes... Quickly, but not for a week or 
two... Sorry. Someone may be able to do it better more quickly, and that 
will be great.

Thanks for this info, too. You've saved me some asking around to find 
out. Now I have more displays to look up! /grin/
