jens, 
Why am I doing this?
In Italian, I need to polish my grammar. When I speak, I forget verb forms and so forth. My understanding is pretty solid by now.
Romanian is my inlaw's language. I understand enough for getting by, but I have little sense of the grammar yet.
Japanese I studied a long time ago, and regret forgetting.
Castellan I needed this summer, and is close enough to Italian that I really have no excuse for not speaking when I understand most.
Swahili? Random African choice.
