Comment 1 for bug 504656

Not sure if your questions were rhetorical or not, but just in case they were not:

1) The purpose of this email is to have a record of all bug activity in email. Some people do like having this -- for searching, having archives of bugs, etc. from their mail client.

2) You can't turn it off because we haven't done the work to make bug mail notifications configurable.

I agree that you should be able to turn off notices of your own activity. I think this should be a single "turn off notices of things I say or do" (yes, I know that isn't a good sentence for the actual option, but you get the idea ;)). With that in mind, I think bug 504663 is a duplicate of this one.
