If you are an administrator of a rather dormant LinkedIn Group, then you may be interested to know how to breathe new life into your community. If you are a member of a group, you will start to see group activity in your notifications tab, and they are also rolling out the ability to add video to your groups.
They give with one hand and remove with another.
LinkedIn gave announcements in January about the new group features and then in February they announced that they will be shutting down the LinkedIn Groups App.
Note: Your existing group memberships and contributions will not be affected as part of removing the app.
