I just submitted a request to be unsubscribed from a mailing list by
going to the list on lists.d.o, putting in my email, and hitting the
"Unsubscribe" button.

The result was the following message:

"""
You have been unsubscribed to the list(s).
I can take up to 5 minutes until we process your request.
You will have to confirm your request.
"""

I think it should say "unsubscribed from the list(s)" (instead of "to")
and "It can take" (instead of "I can").

Best regards,
Niels
