Using the "Personal" site as a starting point, I notice that there is a "Sign out button" wep part control on the page. This control has a "Sign in button settings" section where you can specifiy things such as the "Button text for sign in" and such.

Seeing this led me to believe that if the user was not logged in, that they would see the sign in link (or button). However, this is not the case. What's the magic here? I would think that this would be a pretty straight forward thing - to so the "sign in" link if the user is not authenticated - yet when I sign out - nothing. No "sign in" link at all shows up.

What's the secret here?
