I tried to add a family star to my brother (Van Der Walt-256) with the text: "For a very deserving devoted and inspiring genealogist, researcher, teacher, father, husband, brother - many thanks! ... my jongste klein boetie, nou die slimste van ons almal - Baie dankie. Liefde, Philip." However, I keep on getting the notification that his wiki-id is invalid (even though I've checked and made sure that it is correct).
