yes Adam that's an option if you don't want to type jQuery. each time you uses something from the jQ Library. Hope everyone understands whats going on, here is a little explanation:

Adam tests if jQuery is a valid object and ready to use: if (jQuery)

If the is true he calls a self calling function and pases the jQuery Object. The function parameter name is the $. Within the function you have you're typical jQuery $ shortcut. (function($) { $.globalMethod(); $(selector).instanceMethod(); })(jQuery);

Thanks for for the snippet Adam.
