title: How to reduce the Recaptcha difficulty?
body: <p>I use <a href="http://code.google.com/apis/recaptcha/intro.html" rel="noreferrer">RecaptchaControl</a>, and the users complain that the image is not that clear (the black part in the the captcha is too hard to read). Is there any property to make the image less difficult (less noisy)?</p>
  
  <pre><code> &lt;recaptcha:RecaptchaControl ID="recaptcha" runat="server" PublicKey="XXX" PrivateKey="YYY" OverrideSecureMode="true"  /&gt;
  </code></pre>
