Change how you want to receive notifications about new comments on posts you are following. You can receive notifications via email, mobile, by both email and mobile, or no notifications.
Change whether you want to receive direct messages (DMs) by email, mobile, or by both.
You can turn on or off push/email notifications individually for each group you are a part of. Simply click the downward arrow adjacent to the group and toggle on/off notifications by mobile/email.
