Have you ever had your regular (important) messages swamped by a flurry of notifications for that inane group conversations about match-flavored Kit Kats? Or maybe you want to keep your iPad’s notifications switched on, but you want to mute iMessages messages from your boss until Monday, because she has no concept of boundaries? Then you need iMessage’s handy conversation-muting feature. It’s so easy to use that you may have turned it on by mistake. If you’re no longer getting alerts for certain messages, you may want to check this, too.
