Manager Guide: Digest Settings
To set the user's account to receive digest mail, go to http://lists.uua.org/mailman/admin/listname/members ("Membership Management...") and find the member's email address in the alphabetical listings. Check the "digest" box for that member, then click the "Submit Your Changes" button at the bottom of the page.
If the user seems to be having trouble reading the digest messages they're getting, it's possible their email reader can't handle "MIME" format messages. Check the "plain" box and click the "Submit Your Changes" button.
To set the user's account to receive individual messages instead of digests, uncheck the "digest" box and click "Submit Your Changes."
