Need help with custom validation for jQuery validation plugin
<p>I'm using the jQuery validation plugin found here:</p>

<p><a href="http://plugins.jquery.com/project/validate" rel="nofollow">http://plugins.jquery.com/project/validate</a></p>

<p>In my form I have default values saying "Please enter your name" in the name field.  I'd like a custom validation to ensure that a user has not left this when they submit the form.</p>

<p>Here's the jQuery i'm using.... Can someone please help me with the missing code.</p>

<p>Thanks :)</p>

<pre><code>$(document).ready(function(){

    $.validator.addMethod('defaultText', function(value, element) {
    // need code to go here!!!
    }, 'Please enter your first name'); 

 $("#commentForm").validate({
     rules: {

     firstname: {
         required: true,
         defaultText: true,
     },
     email: {
         required: true,
         email: true
     }
 },
     messages: {
         firstname: "Please enter your first name",
         email: "Please enter a valid email address"
     }
 });

 }); 
</code></pre>
