Well, I'm half Finnish... Don't speak it really though. All I can say is thank you (kiitos), and a few curse words, along with a bunch of weird name pronunciations. Here's a few links though, to learn some basics online. Good luck, its pretty tricky. My grandma is fluent and has tried to teach me some stuff, and it's not an easy language to learn.

And try google-ing "learn finnish online" and you'll find plenty more links, too.
