I know you were looking into studying Japanese, and I'm glad to see you're hopping onto JPLearn! as a good start. :D

Here you can do a lot more though, you can create or join study groups (or fangroups for the matter), there are forums, image galleries, J-Spot social network which is what this is, there are practice apps (more to come and eventually full mobile support), there's the market thingy to unlock new features (lots of free stuff don't worry), achievements, sticker unlock and more. :D

Have lots of fun!
