Uh, right off the top, based on the two things you said about yourself, I know of two places for you. The 'Study Japanese' hangout thread in Clubhouse forum and the art forums. :3

If these don't work out for you, then it's a matter of just posting around and testing out each individual thread to find a niche that suits you best.

I would also suggest that you go to the '10k Cat Paws Charity' thread and sign up as it's a great way to earn old items from them. They work sort of like a Chuck 'E' Cheese in which you earn points and when you have enough, you can trade them in for older, rarer items. :D
