+	TODO: Further optimize serialize function
+
+	UPDATE: We were forced to create an individual XHR for each request
+	to avoid race conditions on slower browsers where the request would
+	be overwritten before the callback triggered, and leave it hanging.
+	This only happened in FF3.0 that we tested.
+
+	Example usage 1:
+	ajax.handle = function () {
+		$('#preview' + postid).raw().innerHTML = ajax.response;
+		$('#editbox' + postid).hide();
+	}
+	ajax.post("ajax.php?action=preview","#form-id" + postid);
+
+	Example usage 2:
+	ajax.handle = function() {
+		$('#quickpost').raw().value = "[quote="+username+"]" + ajax.response + "[/quote]";
+	}
+	ajax.get("?action=get_post&post=" + postid);
