Creating an email group is a great way to keep a lot of people organized without asking them to learn anything new. An email group creates a new email address that reaches everyone you add to the group, and can allow anyone in the group to write back to everyone else.
Email groups are a good choice for wider community to share their memories, grief, and reflections. They are also excellent tools for people who do not use smart phones or apps, as using an email nothing new has to be learned or downloaded to use an email group.
