Hmm... wasn't Huttese and Ewokese based on some genuine languages of African origin? If you want to put that much effort into it, maybe that's the way to go. Take some foreign languages that are totally different from the main languages (English, French, Spanish etc.) and combine them to create something new. Unfortunately, it's not just something you do in one day!

I've been lurking around for a while now, but allow me to say that I'm really impressed with what I have seen from you guys so far. At least someone know how to get these changes right!
