Email notification for those that have only updated an issue?
We're running a somewhat old version of Redmine, so it's possible that the issue we're having has already been addressed in a newer version.
What I'd like is for anyone that has updated an issue -- even if they aren't listed as watcher -- be notified by email when the issue is updated. Quite often one of our users will update an issue they haven't created or are watching, but they don't receive any email notifications of updates.
Automatic addition as watcher on update of an issue would be another way to achieve what we want.
Are there any settings for this desired behaviour?
