The Kiwiburn Facebook Group privacy setting has changed from Public to Closed. Some community members had expressed that they preferred not to engage in discussion on a public forum. A week long poll withing the Group supported the change.
The Group is still easily found when searching, and you are still required to request to join. There are also two questions to answer before being allowed to join, so if you are adding your friends, let them know, and prompt them to answer the questions.
