As of Ares Server v5.0.9/Web DLL v5.0.6, the CAPTCHA tag can be used to display the captcha challenge requirement on the Create Account form (GCreateAccount.html) when a captcha integration has been configured in the Ares Customization Manager. If no captcha integration has been configured in the Customization Manager, then the CAPTCHA tag will only be used to add the Submit button to the form. The tag has no additional specifications.
The CAPTCHA tag can only be used on the Create Account form (GCreateAccount.html). It is not supported for use on any other Ares web pages/forms.
