Login link in Primary Links
The AL - February 29, 2008 - 14:41
I manually added a login link to my primary links. By default, it automatically inherits the child link "My Account." That way the login link gets replaced by it when you log in. Well, I don't need that on the site I'm building. How can I make it so the Login link is swapped with Logout instead?
Try the Login Menu Module
I think the functionality you are looking for is in the Login Menu module.
It shows a login link only for anonymous users. http://drupal.org/project/loginmenu
