The user pref "Only email me reports of changes made by other people" is
confusing, even for an experienced bugzilla user. It would be much easier to
understand if it was "Email me when I make a change". This would be more
consistent with the other two options on the page.
It would need to be "Do not email me when I make a change" instead for one since
the checkbox means that. And this does not sound any less confusing to me than
the current wording. This is also the default wording used by mozilla.org so it
should probably be fined upstream for this one.
