Recaptcha.plugin is a plugin that will use the reCAPTCHA service instead of FUDforum's default captcha challenge. This plugin ships with FUDforum 3.0.0 and later releases. reCAPTCHA v2 support is introduced in FUDforum 3.0.9.
If this plugin is enabled, users will see a reCAPTCHA captch instead of FUDforum's default captcha when registering or posting anonymously.
This plugin uses FUDforum's CAPTCHA and CAPTCHA_VALIDATE hooks.
