Unfortunately, he is a blind linux user, and blind/vision impaired people

I know it is possible to scramble email addresses in the source using JavaScript
but am not sure whether that would work with other URLs, such as form submission
URLs. If it is possible, this might be of some help.

On my page here http://www.speleonics.com.au/mikes/mysoftware.php I have a Spam Obfuscator that inserts a random word into a plain text sentense like an email address. It does not use an image and it changes everytime. It's easy to configure for web forms. The user can be presented with plain text that asks them to insert in the form an anser like this:


Please enter the mineral name goethite. ______
I have a cat. Please enter the animal. ______
Positrons are particles. What was the name of the particle? _____
