Two new CAPTCHA anti-spam/anti-bot modules available
As of 1.1.6.4, Wikka now supports a modular plugin framework for user registration validation. Besides the two modules that ship with 1.1.6.4 (a “dummy” template module and an invitation code module), two new modules have been developed and are available for installation.
Nils Lindenberg’s URTextCaptchaModule. This module requires the user to respond correctly to a random textual question for successful registration.
Brian Koontz’s URCaptchaModule. This module uses the excellent freecap package to generate CAPTCHA images.
As always, we appreciate the feedback on these modules or any other features in Wikka!
I’ve installed the URTextCaptchaModule and it works great ! Accessibility is important for me and this text CAPTCHA is the only *really working* solution for screen readers.
A friend of mine runs a similar script on his forum : never been defeated by spam bots in two years.

Cynthia, great news! Nils will be happy
For those who might be wondering why we are making different CAPTCHA modules available: One of the reasons we decided to go with a modular framework for user registration is that webmasters have different views on accessibility. In an ideal world, every site would be accessible to every individual, regardless of handicaps or impairments. Obviously we’re not close to that ideal yet, so there are varying levels of compromise being made. The framework was designed so that it would accommodate these different levels of compromise.

Does the CAPTCHA module work for posting comments? That seems to be my number one spam problem.

Keith, a Wikka user and frequent contributor, Masin, has the module working for comments. He’s frequently on IRC (channel #wikka on freenode), or you can visit his WikkaWiki page and drop him a note.
