Tài liệu Setting Up Access Configuration

The OG module provides a number of blocks that enable users and administrators to create, join, and
participate in groups. The standard blocks include:
New groups. This block provides a list of the groups that were recently created.
My groups. If the user is logged in, this block displays a list of groups to which
the user belongs.
Group details. This block provides the links for group members to create a
group post, invite a friend, manage their membership, see the number of
members, and the designated group manager.
Group search. This block provides the ability to search content within the
group.
Group notifications. This block enables the group feed options and is active
once the user enters the group.
Group admins. This block provides the same information as in group details,
but directed at the administrator of the group.
Group members. This block lists all of the members in a group.
Group files. This block lists all of the files associated with this group.
For demonstration purposes, I’ll assign every block to the right sidebar of my test site. You may
assign the blocks that make sense to your site to any region you desire
