You can customize the pool of words to display. Features Toggle whether registered users need to enter the word Random font display No cookies required No JavaScript required Auto-generated audio for visually impaired users Easy-to-read No mapping of words from the code — words are used once or removed after 24 hours Reminder of what was entered if you get the word wrong Selective blocking of trackbacks, pingbacks Easy to translate Compatible with caching plugins Negatives Purposely no obscuring techniques so that the anti-spam word is easy to read The more people who use this plugin, the more motivation for spambots to target it Requirements GD Library and FreeType Library (There’s a diagnostic page to tell you whether you have them installed. If needed, just ask your web host to install them!) WordPress 3.2 or higher Translations ru_RU translation by koc sk_SK translation by Patrik Žec (PATWIST) of http://patwist.com
