-	-----------
-	Do not use both ajaxSubmit and ajaxForm on the same form.  These
-	functions are intended to be exclusive.  Use ajaxSubmit if you want
-	to bind your own submit handler to the form.  For example,
-
-	$(document).ready(function() {
-		$('#myForm').bind('submit', function() {
-			$(this).ajaxSubmit({
-				target: '#output'
-			});
-			return false; // <-- important!

-	Use ajaxForm when you want the plugin to manage all the event binding
-	for you.  For example,
-
-	$(document).ready(function() {
-		$('#myForm').ajaxForm({
-			target: '#output'
-		});
