Drupal Commons Nested Groups - repost

I need someone to add the following groups and sub-groups to my site, and then write instructions on how to do it: i.e. Top Group: Nurseries/Kindergardens - Sub Groups: Poppies Day Care, Toad Hall Childcare, Little Stinkers Nursery - - Sub Group per team: Parents Forum, Staff Only, Questions, Public All of the sub-groups need to have their own permissions. The 1st level sub group should be able to be searched for on tags (the tags will have nursery name, location etc.) I will give you access to my site to add an example and then you can send me the instructions via emails Thanks
