All users can create a group, as of now.

When you participate in a group the posts in your blog can be shown in the Wall of the group.

Groups can sustain proposals, create new ones, create surveys and organize members using roles and permissions.

It is possible to change the rules of this group through its Settings.

• Participation:
When a user requests to participate in the group, only group administrators are allowed to do so. Once the administrator has accepted the request, the user will be a full participant in the group.
