-	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() {
-			$(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'
-		});
-	});
-
-	When using ajaxForm, the ajaxSubmit function will be invoked for you
-	at the appropriate time.

+	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.

+ * 2. This method will include the submit element's name/value data (for the element that was

+ * 3. This method binds the submit() method to the form for you.
+ *
+ * The options argument for ajaxForm works exactly as it does for ajaxSubmit.  ajaxForm merely
