Who here is fluent in a foreign language? And what is it?

I only speak English but there are several languages I want to learn. I downloaded Rosetta Stone (with all the languages) a while back and I need to install it on this computer. I've used Rosetta Stone in the past. I tried to learn Dutch but I lost interest after a month. For 2012, however I'm going to get serious about learning a new language. I haven't decided what I'm going to study, but the languages on the short list are Spanish, Japanese, French, and Mandarin. I want to learn Finnish but fucking Rosetta Stone doesn't offer that language yet.

My hopes in making this thread is that at least one person here can fluently write one of those languages and then agree to correspond with me for practice.
