 * After toying around with Prototype, I decided to take a look at jQuery and in
   particular the jQuery Validation plugin:
 * [http://docs.jquery.com/Plugins/Validation](http://docs.jquery.com/Plugins/Validation)
 * I have hit a snag with loading the built-in version of jQuery using `wp_enqueue_script('
   jquery')`. The `$()` functions return “property does not exist” errors. I noticed
   in the header of the Admin pages that they make a direct call to `jQuery()` to
   work with the dashboard feeds.
 * My workaround so far has been to just load in a vanilla version of `jquery.js`,
   but I am curious if there is a general guideline for using jQuery in WordPress
   plugins or themes that would differ from the native documentation and tutorials.

 * You should use the jQuery() function as opposed to the $() function alias. I 
   believe that WordPress goes ahead and calls the no conflict function to restore
   the $ alias to whatever it was and then reverts to using the jQuery() function.

 * That appears to be the fix. I suppose all is well in the interest of playing 
   nice with other libraries.
