Overview
- Admins can initiate the privacy change from a group's settings, with the rollout beginning today.
 - Other admins are notified and have a three-day window to review or cancel the conversion before it takes effect.
 - Content shared while the group was private remains visible only to pre-conversion members as well as admins and moderators.
 - After conversion, only admins and moderators can view the member list, and members receive notifications plus first-post reminders about public visibility.
 - New posts, comments, and reactions become publicly viewable, which could enable search engines to index group content, and groups can later be reverted to private.
