For any not aware, Karen Traviss has come up with a whole dictionary's worth of Mando'a.
Word of caution - LucasFilm does hold the copyright over all the Mando'a, so we can't just go posting up the whole dictionary wherever we feel like it or trying to profit from it in anyway. The dictionary and grammar file are both available via Karen's website (www.karentraviss.com).
