TracCaptcha 0.1

TracCaptcha is a trac plugin to embed a captcha in the ticket page in addition to Trac’s regular permission checks so that spammers are kept out.

Batteries included: The popular reCAPTCHA system is supported out of the box. Technically it’s a plugin - if you don’t like it you’re free to use any other plugin while still leverage the benefits from the general captcha infrastructure.

Does not annoy users: After the user entered the captcha once, he does not have to solve the captcha again for the same ticket when he just clicks ‘preview’. Also you can configure exempt certain users or groups (e.g. ‘all authenticated users’) from the captchas just by using Trac’s permission system.

Generic Infrastructure: TracCaptcha takes care about embedding a given captcha in the appropriate places which means that building a different captcha plugin is easy - you just have to build the captcha itself while this code will take care of the trac integration.
