    Dear Mr Cardoza,

    I’d like to use your wonderful CAPTCHA plugin as the basis to build on, in order to create a different kind of Captcha.

    Would this be okay with you? (I would, of course, credit you fully for the original code, along with links to your site and plugins.)

    Please let me know if this is okay with you.
