Captcha extensions

There is more than one way to insert Captchas into MediaWiki.


 * The ConfirmEdit extension uses FancyCaptcha
 * The extension uses its own captcha.

Captchas can be used selectively for : file uploads, edits to particular namespaces, user account creation, user login, all but the first five edits in a given five-minute period.

Likewise, they can be used in coordination with user or IP whitelists...
