notCaptcha is an unconventional captcha mod that requires human intelligence to be solved. Instead of entering some hardly readable text from some ugly picture, the user needs to spin pictures into the right position. It's easy for every human and nearly unsolvable by a computer.
- easily solvable
- funny pictures
- ability to use your own pictures (highly recommended!)
- currently not cracked by any spambot (if using custom pictures)
- unsolvable by visually handicapped people
- mobile users cannot register (e.g. IPhone)
Use your own pictures
Download the createOwnPics_INFO.zip file.
You will find a readme.txt and a template.psd.
See the readme.txt for information on how to create and name your pictures properly.
Using your own pictures instead of the included ones will significantly increase security of this captcha!
You can have a look at the notcaptcha/gallery directory of your SMF installation for examples.

If you're using the default theme there is nothing to do other than installing the mod via the admin interface.
But you might want to have a look at notcaptcha/notcaptcha_config.php for some custom settings.
If you are using a custom theme you need to edit one to two files. (Register.template.php is not included in every template and so does not need to be changed manually)
index.template.php (for SMF 1.x and 2.x)
// add notCaptcha code
Register.template.php (for SMF 1.x)
// add notCaptchabefore
echo '<tr><td width="40%"><strong>'.$txt['notcaptcha_form1'].'</strong><br />
<div class="smalltext">'.$txt['notcaptcha_form2'].'<img src="'.$modSettings['notCaptcha']['url'].'vertical_sign.png" alt="^" border="0" /></div></td><td>
<div style="display:block;padding-bottom:5px;" id="captchaImgDiv">';
// Are there age restrictions in place?
Register.template.php (for SMF 2.x)
The mod should install fine for SMF 2.x as it supports modifying all installed themes. Else you need to parse the install_2.xml by yourself and figure out where to put the code.
