The MediaWiki Captcha, ConfirmEdit (SimpleCaptcha), for MediaWiki 1.15.0 has been installed on the wiki associated to this board.

A Captcha is a security measure designed to require user-interaction and hence disallow automation from accessing the restricted functions. This usually is by presenting a question or image to the user who must then provide an specific answer that may be calculated or read before allowing the wiki function to be used. The ConfirmEdit captcha will require new account creations, failed login attempts (3+) and addition of urls to content to calculate a simple equation and provide the answer in a text field.

The delivered ConfirmEdit captcha provides a simple equation of the form 'x + y' or 'x - y' where X is between 0 and 100, and y is between 0 and 10, with plus or minus being randomly selected.

To avoid automation that may be able to 'read' the delivered protection, the equation generator has been customized to show equations of the form (x +/- y) * z +/- t. In this, all plus/minus operators are randomly selected, the multiplication sign is constant, and x in the range of (0 to 100), y (0,10), z(3,20), t(1,100).

Please post here or contact system admin if any problems with this extension.

(Note: other captchas are available and can be reviewed for suitability and security. Also, since the wiki and phpbb run on different extension formats, the captchas used for one system are not delivered compatible with the other. Hence, different captchas for both board and wiki without significant work to rewrite any desired one in the other system's format)
