drupal 7 organic groups and subgroups

has anyone used organic groups in drupal 7 with subgroups -- I downloaded organic groups, but when added subgroups I don't see any of the screens or selection lists I am suppose to get for parent, child etc.

have parent groups which will have subgroups and want the administration handled by the parent or someone in the parent group.

Anyone worked with this or these.

Any help is most appreciated
