On my user prefs page, under the "Miscellaneous" heading, I spied this:
- Is the second option talking about email notifications or some other kind of notification?
- Why is one checkbox an opt-in and the other an opt-out?
Assuming both refer to email notifications, I suggest it may be less confusing to change the header to "Email Notifications" and invert the state/label of the second option.
(And yeah, I know this is a silly nitpick.)
