Notifications
That is confirmed
You will get one message when something new is documented, and nothing else. No newsletter, no digest, no appeal.
The next message will arrive when a report is added to the collection, when the project log records something that changes what this site claims, or when a result is published, including a negative one. If a month passes with nothing documented, you will hear nothing. That is the list working, not the list broken.
Every message carries a link that removes you, and using it deletes the address rather than marking it inactive.
If you would rather not be on a list at all, the feed carries the same notifications and tells this project nothing about you.
