Thanks for the plugin wich is very usefull.
I noticed a bug using it with WP3.4/3.5, BP1.7, BPP2.2.3 : when using the "Save Groups" button in admin page, all forum link to groups are always disabled. Each one must be reactivated on admin page. Since i have a lot of groupe it is annoying.
I managed to patch the plugin to avoid the problem :
index.php::bp_group_organizer_admin_page() line 257
$group_reference->enable_forum = isset( $group['forum_enabled'] ) ? true : false ;
$group_reference->enable_forum = isset( $group['forum_enabled'] ) ? $group['forum_enabled'] : $group_reference->enable_forum ;
wich will keep the original value if args is not present and not always disable forums.
Hope this could help.
