I don't know for other team. For french translator, I'm the only one.
On acknowledgements: Stannis was the french beta tester, he often helped me to find errors, he really deserves it. The site Garde de Nuit and specially Lord Riusma helped me a lot to find official translation for little counties and Houses. It was an honour because Lord Riusma is one of the two guy of the site who help the french translator of the books.
