title: jQuery Validation plugin minLength for checkboxes
body: <p>this is my first post here on stackoverflow and am very impressed by the site!</p>
  
  <p>My question is about the jQuery Validation plugin...specifically about the <code>minlength</code> method.
  I have a group of checkboxes and I want to know if at least 2 boxes were checked.</p>
  
  <p><a href="http://docs.jquery.com/Plugins/Validation/Methods/minlength#length" rel="nofollow noreferrer">http://docs.jquery.com/Plugins/Validation/Methods/minlength#length</a></p>
  
  <p>at this link there is documentation about the <code>minlength</code> method being used with a regular input box, but not a checkbox. Can anyone help me on how to use if for checkboxes?</p>
