Hi,
How I want to have a script to generate and check a turing number. A turing number is a number the user has to read and copy in order to be able to validate a form. This avoids automated submissions. Just like when you register for yahoo mail etc it asks for this number to prevent automated registrations. Any help is appreciated.

Thanks

Maybe check out how these do it (If you are really interested in creating your own techniques)?
