Since the question just arose, I have just been working on a new sticker for Belgian Roots. It could be used on profiles of Belgian people and people with Belgian ancestry.
For now the language switch only covers French and... Dutch, though I hope (perhaps with the assistance of our magician) to have it available in at least three languages, English, French, Dutch, and if possible German as a fourth option.
See it in action in French: Violette Roothooft
In Dutch (which should really be in English, and will be changed to English, but I wanted to see it in Dutch): Andréa Dequeker
Please answer to this thread if you would be interested in such a sticker, so that we can get it approved !
