Folks, I'm just a wonderin' what exactly you would like to see here? Please post your ideas and comments on this thread. Whether you want to review something or whether you don't fully understand something, let's try and get to the bottom of it!

So far, I've only got requests for giongo (擬音語） and gitaigo (擬態語）
