If not, then there needs to be awareness of what kind of test to provide based on your expected audience, and possibly a decision tree for coding a test based on something about the client browser. A simple example would be that if you can tell the browser supports images, assume the person can see and give an image test. Otherwise, give a simple quiz that's pretty universal or maybe customized based on a country code earlier on the form. This sounds like a good topic for an eVolt article! Or probably someone on another site has already written one. - John -- This message may contain information which is private, privileged or confidential and is intended solely for the use of the individual or entity named in the message.
