I again Oscar - apparently I am already subscribed to the Tutor list with
this email also:

'An attempt was made to subscribe your address to the mailing list
tutor at python.org.  You are already subscribed to this mailing list.'

I control the spam filter for this domain, so I am not sure why I am not
getting the updates.
