[Plugin: Welcome Pack] Getting js error on the email admin

Hi!

I just downloaded the plugin and tried it out on my site. I get a js error saying that jq is not defined. I rewrote the js to this

(function($) {
	$(document).ready( function() {

		$('.if-js-closed').removeClass('if-js-closed').addClass('closed');

		if (-1 === window.location.search.indexOf('tab=emails'))
			postboxes.add_postbox_toggles('buddypress_page_welcome-pack');
		else
			postboxes.add_postbox_toggles('buddypress_page_welcome-pack-emails');

		$('div.initially-hidden').each( function() {
			$(this).hide();
		});

		$('#dpw-admin-metaboxes-general input').click( function() {
			var button = $(this);
			var config = $('div.setting-' + button.attr('class'));

			if ( 1 == button.attr('value') )
				config.css('background-color', 'rgb(255,255,224)').slideDown('fast').animate( { backgroundColor: 'rgb(255,255,255)' }, 1600);
			else
				config.stop(true).slideUp();
		});

		$('#emailpicker').change( function() {
			var index = this.selectedIndex;
			if ( 0 == index ) {
				$('#email').hide().empty();
				return;
			}

			$.post( ajaxurl, {
				action: 'dpw_fetch_email',
				'cookie': encodeURIComponent(document.cookie),
				'_wpnonce': $("#_ajax_nonce_dpw_emails").val(),
				'id': index
			},
			function(response)
			{
				if ( response[0] + response[1] == '-1' )
					return;

				$('#email').html(response.substr(0, response.length-1)).show();
			});
		});

	});
})(jQuery);

and that works. Unless jq was intended as something different than a shorthand for jQuery then the self execution wrapper is the recommended way of doing things.
