TK Reminder is a plugin that will show a notice on the admin panel telling you 
if you have pending reminders. It will also make the <code>Publish</code> button a different 
color to call your attention.
Important: TK Reminders will not block you from publishing, it will just 
make it visible that you have reminders in your post but if you wish to publish 
with them you can still do so.
