I have been searching the net to try to find a script i may use that would use a generated password verification script - to type in when sending email on a form - to stop automatic scripts from submittng the form. I would prefer a javascript to do this but i don't know if one exists.

To see what i mean, take a look at - http://www.sulekha.com/classifieds/c...d=8929&nma=PDX

You will see at the bottom on the page they have a email form which requires that the user types in a automatically generated password for the email to be sent. Some search engines have been using this method when websites submit their url's.

Does anyone here know if there is a free script out there that does this?

Thanks for any help in advance.
