You're trying to combat spam, which is your problem as a site admin. Your solution to this is to make it the user's problem, by challenging with a test. If the user cannot pass the test because of a disability, your user is going to be pissed you might be in hot legal water. The test serves no functional purpose and keeps users with a particular disability out. > A simple example would be that if you can tell the browser > supports images, assume the person can see and give an image test. Bad assumption. There is little or no correlation between whether the user agent supports images and whether the user has a visual disability. -- Matt Warden Cleveland, OH, USA http://mattwarden.com This email proudly and graciously contributes to entropy.
