Hi, I'm not expecting this list to become quieter - to help avoid missing important conversations, please make sure the subject line of your message matches what you're talking about.
The usual convention is to use "foo (was:bar)" as the subject line when a thread that started with "bar" starts talking about "foo". Also, don't hesitate to split your reply into several ones with distinct subject lines if you're talking about several things at once. One topic per thread is much easier to manage. -Bertrand
