#190837: User should not be able set a parent for non-subscribed group (access bypass). Thanks Amitaibu for pointing this out.

#223481: Repeated use of arg() function in og_subgroups_menu() is inefficient - replace with single call and a variable.

#218747: Parent not Saved when Post Propagation Direction set to None. Thanks to torelad for the initial troubleshooting

Corrections for Drupal coding standards in hook_menu. Localization as per http://drupal.org/node/160006.

Added access control for editing subgroups and member list.

This version removes the use of the taxonomy module and incorporates the og_ancestry table.

In accordance with http://drupal.org/node/83124#comment-139112, the order of members and subgroups in a tree is flipped.  Also, inaccessibility of a group to a user is handled better.

Fixed the bug reported in http://drupal.org/node/82298 #2 and (same bug) http://drupal.org/project/comments/add/82375 #1.

In response to the bug report filed in http://drupal.org/node/82298, I modified og_subgroups_get_effective_groups to return groups as arrays.

I've created this module to provide subgroups for organic groups.  This is my first time using CVS or contributing to Drupal, and this is the first draft release of this module.  If there's something wrong with the module or its being put here in this way, I apologize and would appreciate feedback.  My username is 'donengel'.
