How do I choose what I’m notified about in a Facebook group?

 To choose what you're notified about in a group:

1. From your News Feed, click Groups in the left menu. If you don't see Groups, click See More.
2. Click  in the top left and select Customize notifications.

From here, you can select:

• All Posts: You'll get notifications any time members post in the group.
• Highlights: You'll get notifications for suggested posts and posts from your friends.
• Friends' Posts: You'll get notifications whenever your friends post.
• Off: You won't get notifications when members post.

Note: When you join a group, its notification setting will be set to Highlights by default.
