If you already subscribed to the new Wi-Fi Networking News mailing list, you can now set digest mode: Sorry about the difficulty, but you can now set the digest mode for the mailing list so that you receive a single message each day containing that day's posts.
This didn't work earlier today, but has been fixed. Send email to firstname.lastname@example.org with just the words:
set wifinetnews digest
in the body of the message. You should receive confirmation via return email.
