title: jQuery-Validation-Engine -- Making sure fields values do not equal
body: <p>I'm using <a href="https://github.com/posabsolute/jQuery-Validation-Engine" rel="nofollow">jQuery-Validation-Engine</a> to do some client side checking before sending a form to the server.</p>
  
  <p>I know you can check to make sure two fields match using <code>validate[equals[fieldId]]</code> where <code>fieldId</code> is the id of the field you want to match.  Useful if you want to make sure passwords match, for example.</p>
  
  <p>Now I am trying to find a way to make sure fields <em>don't</em> match.  For example, if I wanted to make sure a password field did not match a username field.</p>
  
  <p>Has anyone been able to get this to work?  Any other ideas?</p>
  
  <p>Thanks.</p>
