One thing I think might help is using the plugin “menubar”. It has a feature where you can add php code to make a menu item. So you add this to add a login for example.
if (is_user_logged_in ())
return array (‘Log out’, wp_logout_url ());
else
return array (‘Log in’, wp_login_url ());
Now it would be really useful if someone could give some examples on what to enter to make it go to a users activities, profile, etc.
