I found this on Digg.com- Mango. It’s a language learning program- totally free. It looks very similar to Rosetta Stone (which by the way, is often available through your public library).
I haven’t had time to play around with it much yet, but it seems like a pretty solid learning tool. So if you want to learn Polish, Mandarin Chinese, or Brazilian Portugeuse, check it out.
They also just added a Pig Latin course. With 61 Sections. Crazy people exist in this world, that’s for sure.
