I say welcome to you all to the best English Japan forum you can find on the web!!!
For Japanese, you can use the JREF top page menus "Language."
and
1. "Learning Japanese" forum.
As for other stuff, the popular and generic forums are
2. "All things Japanese" on the top
3. "Gallery" forum
4. "Chit-Chat" forum
For any trouble you are having, you can PM anybody with "Mod" "Admin" "Tutor" "Advisor" or post something on
5. "Support Request" forum
Of course, feel free to dig around. The search function is good, too, but if you don't find anything there, don't give up either. Some things don't show up in the search. There's so much stuff here you won't believe. JFORUM is like an encyclopedia that's been growing on its own; really amazing!
Also post your ideas when you feel like it, and don't be afraid to start new threads and polls. Really nice feature that I enjoy a lot. I hope you do, too.
Have fun
