Hey, look at this file: http://trac.cotonti.com/browser/trunk/plugins/markitup/markitup.ajax.php
For AJAX use Hooks=ajax, not Hooks=standalone. You only need 2 files: notificatons.setup.php, notifications.php All the other files just does nothing so why you make them?
Also in notifications.php, make one loop instead of two...
Anyway, nice idea. Keep it up :)
