Thanks!, I hope it is good. Well, in your message, "duo lingo" is the subject, what you are talking about, so you say "is" instead of "it's". Also, you should say "very good"...I make plenty of mistakes myself¡ ..and ya I will use this site. Thanks for your support, mon ami

Hi :D I think DuoLingo it's veeeery much good, but it's just theory and theory, use it, but use this site too! Talk with people always will be best than just theory :D (if there's some error, sorry, haha)
