I’ve just posted new captcha plugin to list of symfony plugins:
http://trac.symfony-project.com/trac/wiki/sfCaptchaPlugin
The `sfCaptchaPlugin` is a symfony plugin that provides captcha functionality based on JpGraph library. It gives you the lib and the module to secure your symfony forms in a minute with a good captcha. This plugin minimize time which has to be spent on captcha integration and detailed instruction is available for developers.
If someone has any comments or ideas about improvement would be really nice to hear that.
Thanks in advance!
