Notes

TNG enabled the capability for a captcha mod by doing a conditional include for TNG_captcha.php since TNG 6.0.

While TNG has continually updated its security options, the captcha does eliminate spam suggestions, user registrations, and comment messages.

Once installed the captcha mod does not require a rework for TNG new releases and upgrades since the include is part of the suggest.php and newacctform.php code provided by Darrin. Thanks to Brian McFadyen who made this happen.

@include($cms['tngpath'] . "TNG_captcha.php");

Different captcha mods are available:

• Brian McFadyen's mod which uses the freecap software
• Roger Moffat's mod which uses the reCAPTCHA software developed by Carnegie Mellon University and now managed by Google - this is now outdated v1.
• Bryan Larson's No Captcha reCAPTCHA Add-on - this is a new version of Google's reCAPTCHA tool - this is current v2 and is obsolete in TNG v12 since it is now part of TNG v12+
• Bryan Larson's NuCaptcha Add-on - Obsolete in TNG v12 since it is now part of TNG v12+
• Rick Bisbee's Image Captcha Add-on
• Mike Bluett's Slider Captcha Add-on

Brian's version

Brian McFadyen's version uses the freecap software to provide the captcha challenge and is the original captcha mod

Pro	Con
Provides multi-language support	Freecap is hard to read when visually impaired and may require choosing new words multiple times before the challenge word can be read

Roger's version

Roger Moffat's version uses the word challenge capability from Google's reCAPTCHA: Stop Spam, Read Books page. As of version 8.2.0 it also supports switching the "theme" of the widget and provide support for a number of different languages as supported by Google.

Pro	Con
The word challenges are easier to decipher for visually impaired (color-blind) users.	Multi-language support is provided by Google - oh wait - that's a Pro now. Version 8.2.0 implements the Google codes for multiple languages.
An audio capability is provided	Requires that you have or establish a (free) account with Google, and request a private and public key, which is not really a big negative.
Every reCAPTCHA challenge correctly answered helps digitise olde books and newspapers - the words provided by the challenge are taken from books and newspapers that are being digitally archived and indexed.	The same keys will work on their assigned domain, AND on localhost or 127.0.0.1. Or you can take advantage of a feature added by Google to get a "Global" key that will be your key to work across multiple domains, meaning you only need a single pair of keys for many domains and your localhost.

• Our Acadian, French Canadian, and Maine Ancestors I used Brian McFadyen's captch mod for over two years but have switched to Roger's since the challenge text is easier to interpret, and now am using Image Captcha Add-on because Google has made it more difficult to decipher the reCaptcha challenge.
