Thanks for getting syzbot to classify reports by subsystem and send these
reminders! These should be very helpful over time.

One thing that is missing in these reminders is a mention of how to change the
subsystem of miscategorized bugs. Yes, it's in https://goo.gl/tpsmEJ halfway
down the page, but it's not obvious.

I think adding something like "See https://goo.gl/tpsmEJ#subsystems for how to
change the subsystem of miscategorized reports" would be helpful. Probably not
in all syzbot emails, but just in these remainder emails.
