5.3-BETA1 released today for testing

[JJB]

 http://www.freebsd.org/releases/5.3R/schedule.html  says that the
5.3-BETA1 tier-1 platform images are scheduled to be released and
uploaded to ftp-master.FreeBSD.org by Aug 20, 2004.

The ftp-master.FreeBSD.org server does not accept guest or anonymous
logons.

Is the testing release of 5.3-BETA1 behind schedule allready and not
yet on ftp-master.FreeBSD.org?

How can people get 5.3-BETA1 miniistall.iso image for testing?

What is the status of this testing release and how do people get
access to help out in testing?
