Redmine

Just go to your account page and check the box : I don't want to be notified of changes that I make myself

Putting this by default might not be wanted by everybody ...

What could be done could be in the settings add a checkbox under the "Default notification option" named "I want default notification for the changes I do" which would change the default behavior for any new account and it would be a feature request.

I'm sorry for reviving the dead, but I don't think this issue should've been closed. This issue discusses the default value for this setting, and the fact that it can be manually changed is assumed, and actually unrelated.

I think not being notified by the changes I made myself is a much saner default. I've introduced many novice users to Redmine, and most of them complaint that they receive too many superfluous emails from Redmine until I teach them to change this setting. It's just bad user experience.
