New version of the Google Account page
This has probably been around a while but I have never seen it. It shows you all the services that you are signed up for and has links to them. It also has lists of other Google services you can sign up for. It does have a link where you can Close account and delete all services and info associated with it.
To see the old version go to.
You may have to reload it a few times. It shows the new version some of the time.
