| Platform administrators can either create their own individual groups or use existing groups from other platforms. In order to use an existing group from a platform ("original platform") on another platform ("concomitant platform"), the s-admin needs to make some settings. (related topic: Included groups )
 
 Shared groups differ from individual groups in the following points:
 
 
  In the interface area "Groups & Users" > "Editing groups": 
  
    The group title is written in italic letters in the interface of the concomitant platform.
 
In the concomitant platform, p-admins are able to remove shared groups from their platform. This
doesn't affect the original platform or any other concomitant platform. 
 
It is not possible to hide or unhide shared groups on a concomitant
platform.
 
Title and description are only changeable in the original platform.
 
Users
can only be removed from shared groups on the original platform. In
this case, the p-admin of the original platform needs to be contacted.
 
Users can be added to shared groups on both, the original and
the concomitant platform. [This is essential! Otherwise users of the
concomitant platform would need to register on the original platform as
well.]
 
 
  In the interface area "Groups & Users" > "Automatic group assignment": 
  
    Shared groups are displayed in the interface for automatic group assignment.
 
 
  In the interface area "Groups & Users" > "All groups & users": 
  
    Shared groups are not displayed in the interface "All groups
& users". [Otherwise, you would have to list users which are not
registered on the concomitant platform but on the original platform.]
 
 All groups & new users: Here are shown the new registered users of the last 30 days.
