Should time permit I hope to work on MyCaptcha 5.2 this weekend.
Planned features:
I promise MyCaptcha won't be about 'APIs'; I will focus on the "Just Works" principle.
A 1.0 version of the alternative CAPTCHA module, MyCaptcha, has been released for Drupal 5.x.
Features:
For additional information, please see the MyCaptcha manual.
Update: MyCaptcha 1.0 has been released.
I've been adding some settings to the math captcha module I created earlier. An important setting is on which forms you want to have a captcha. While it is possible to hardcode the possible forms a captcha can appear on, I've opted for another approach.
I've created two helper modules called Form store and Form collect. If you enable Form collect, it will collect forms on your site while you visit them. You can view the collected forms on the Form store page. In the image below, you can see that I limited the collection to forms I thought useful for Captcha and that I've given most a more readable description. While I intend to include and add a description to all core forms, this has to be done manually for now.
This morning I broke down and wrote a simple math captcha module (for Drupal) to use with user registration and anonymous commenting on this site.
Because this site uses caching for anonymous users, the module needs to make sure that whenever a captcha is displayed, the page is not added to the cache.
