Right now, if you want to invite a user from another organization to your group, you have to either make your content editable by the public, or stop allowing your group members to edit each other's layers. However, I need to allow my group members to edit each other's layers, but I don't want an unknown public to edit our layers. I also need to invite user from another organization to join my group. This is not possible now, but should be make possible. Thanks!
