I need to put a link at the end of the wordpress navigation. It is for my password protection plugin and will create a logout link. It needs to work with or without WP 3.0 menus. Is this possible? If not how do I add one to the end of a WP 3.0 menu? Basically it will be a link to the homepage with ?action=logout on the end. I obviously know how to do this via the admin panel but need to do it program-ably.
