-	Usage Note:
-	-----------
-	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(e) {
-			e.preventDefault(); // <-- important
-			$(this).ajaxSubmit({
-				target: '#output'
-			});
-		});
-	});
-
-	Use ajaxForm when you want the plugin to manage all the event binding
-	for you.  For example,
-
-	$(document).ready(function() {
-		$('#myForm').ajaxForm({
-			target: '#output'
-		});
-	});
-
-	When using ajaxForm, the ajaxSubmit function will be invoked for you
-	at the appropriate time.

+   });
+
+   You can also use ajaxForm with delegation (requires jQuery v1.7+), so the

+
+   $('#myForm').ajaxForm({

+   When using ajaxForm, the ajaxSubmit function will be invoked for you
