( #3333=superdoc: print w/ replies, xml ) Need Help??
I am writing some web stuff in perl-CGI, I need to have an account registration page, I want to verify it is a real person and not a script the same way most sites do with an image containing random text that has been scewed so an OCR program cannot read it. I am wondering what the best way to accomplish this is.

P.S. I am a teacher, one of my students is blind, he informed me that many sites now also offer an audio alternative to the image, does anyone know about those as well?

Thank you!
