Gab Captcha 2 is an efficient and simple captcha plugin for Wordpress comments.
It adds an easy turing test before each comment form. The turing test consist in typing the characters that appear emphasized and red in a text field. The plugin will add an entry in your Wordpress administration area to let you configure some options.
Gab Captcha 2 currently comes in two languages: English (default) and French. You are welcome to propose your own translation or to update existing ones, especially the English one as I am not a native English speaker.
Important notes:
This section describes how to install the plugin and get it working.
Optional but recommended :
You will now receive an email only after a valid comment has been posted.
== Frequently Asked Questions == = Is Gab Captcha unbeatable by spambots? = Definitely not. But it stopped all my spam as of today (getting about 100 spams every single day). = Can I change some settings for Gab Captcha 2? = Yes. Go to the 'Settings > Gab Captcha 2' menu in your Wordpress administration area. = Why Gab Captcha 2 is not translated in my language? = Most probably because nobody submitted a translation for your language yet. But you can help: 1. Copy and paste the file "lang/default.po" and rename it to "lang/gabcaptcha2-code" where "code" is your language code (eg, it is "fr" for French) 2. Use Poedit or any other tool able to handle .po and .mo files 3. Then send me your translated file. Note: do not edit .po files by hand. Use an appropriate tool. == Screenshots == 1.
