This site is one of the neatest ways to practice writing in a language. It's more or less a complete rip-off of mixi.jp, but geared toward language learning. You write journal entries in the language you are learning, and native speakers of that language can make corrections to help you. You can also make corrections to other users who are learning English or any other language you speak.
It's quite useful and incredibly easy to use. It's especially good for anyone learning Japanese, because it seems like that's where most of the activity is coming from. I've noticed a lot of Korean, too, but not so much in, say, Spanish. Still, join up and see what comes.
Just a recommendation.
Hey, thanks for that.
I started using lang-8 myself, after seeing a thread on /jp/
