There are many ideas about when users would like to be able to send email automatically from within the system. This page has been created to discuss each use case. This page is not to be conflated with NagEmails, which are captured separately since they are about times the system needs to notify users that work needs to be done/is delinquent vs. users communicating with one another about any particular topic.
See Issue 495 Comment 13 as a jumping off point for use cases.
