Sender Avatars or Photos in Digest
The Digest version can display an avatar or photo for each person who posted a message to the List. These photos are connected to Gravatar, a free service that provides an avatar for use online.
The photo is helpful for remembering people met at in-person conferences & meetings, Zoom calls, etc.
If Mailing List members have not posted their photo or avatar at Gravatar, a blank silhouette is shown.
This is a free service for website owners, developers, and users. A WordPress.com account is required in order to utilize the Gravatar service.
For more information, please visit the Gravatar web site - How to Sign Up for an Account.
