The installation of the Guestbook Captcha requires two steps.

1. Upload the Simple Captcha Class into the classes/simplecaptcha directory.
2. Install the Guest Book Captcha Hack using the backend menu or upload the files using FTP and overwriting your existing Guest Book Files.

Important:
The GuestBook Captcha will not display the captcha code or function properly without the simplecaptcha class installed.

Limitations:
Cookies are not activated for the GuestBook form . This blanks the forms if an invalid Captcha is entered by the user.
