reCAPTCHA is a Vanilla extension that adds reCAPTCHA validation to a forum's membership application form. A new user applicant must answer the reCAPTCHA challenge correctly or the application will not be submitted.
In order for Vanilla to recognize an extension, it must be contained within its own directory within the extensions directory. So, once you have downloaded and unzipped the reCAPTCHA files, you can then place the folder containing the default.php file into your installation of Vanilla. The path to reCAPTCHA's default.php file should look like this:
/path/to/vanilla/extensions/reCAPTCHA/default.php
Once this is complete, you can enable reCAPTCHA through the "Manage Extensions" form on the settings tab in Vanilla.
The easiest way to change reCAPTCHA's settings is to install and enable Set List. Once you enable Set List, forum administrators will see a link to reCAPTCHA in the side panel of the Vanilla settings page.
If you choose not to install Set List, you can change reCAPTCHA's settings
in the Vanilla conf/settings.php
file.
Theme developers take note: The reCAPTCHA box is a bit large (about
320x140 pixels). If you need to tweak the application form in your theme to
make everything fit, add a reCAPTCHA.css
file in your theme's
styles directory. This style sheet will be added automatically at the end of
the style sheet list only when reCAPTCHA validation is being used.
