Since the “reforms” that occurred on Facebook in terms of the functionality and the role of Pages (Pages) and Groups (Groups)) were confusing to many, here are some explanations about how these tools are designed and what they are for now:
Group members can be notified by email when other members publish information in the group.
The group administrator can send email to group members.
You can create secret groups (not visible in Facebook search), closed groups (visible in the search, but users can join the group only at the invitation of group members), open groups (visible in the search, everyone can send a request to participate in the group. But! group administrators must approve all requests to participate in the group!).
Members can choose how they want to be notified about new messages in the group. They can receive notifications by email and on Facebook.
Personal profiles of group administrators are visible to group members.
Old Groups
Now it is impossible to create a group of the old format.
