I must say that most of the things written in that topic are extremelly wrong! I know this because I've been in a french school since I was two years old, and I doubt someone here would speak better French than myself since it's basicly my own language. Not to think that much of myself, but I corrected some of them in that thread, last topic, so if you are interested, check it out. I didn't correct everything because it'd take too long, so yeah..
By the way, I could do a basic of Portuguese. Let me know if you'd like it.
