5.   Adjourn

Because of toll fraud issues MIT has been experiencing, I've been asked to
change our call coordinates and password and, as an ongoing thing, not
distribute the call coordinates publicly. That means not including the WebEx
call number or URL in our agendas or minutes.



You can find the new call coordinates at this link, accessible with your W3C
member login credentials.
