title: Validating multiple checkboxes using jQuery validation
body: <p>I am trying to take a number of checkboxes and make sure at least one of these checkboxes is checked using jQuery validation. I haven't had any luck so far. What am I missing? I know my validation is there because it works for other fields, just not for my checkboxes. I put up the code on <a href="http://jsfiddle.net/stasis/ZDz59/" rel="noreferrer">jfiddle</a>, maybe this will help.</p>
  
  <p>EDIT: I added brackets for my input name=list parameter (list[]). Also in my rules I changed the name parameter from list to 'list[]'. My old code is below. Thanks Sparky!</p>
  
  <pre><code>OLD: &lt;input type='checkbox' name='list' id='fullProduct'&gt;&lt;/input&gt;
  
  FIXED: &lt;input type='checkbox' name='list[]' id='fullProduct'&gt;&lt;/input&gt;

  <p>Here is my code.</p>
  
  <pre><code>$("#tradeForm").validate({
