This is probably a long shot, but I'd thought I'd suggest it anyhow.
It would be nice to have transcripts (in Japanese of course) of the verbal exchange between the hosts when they are talking to each other during the lesson. Often times the stuff they say to each other is quite entertaining. I don't always catch everything that is being said, so it would be nice to read it.
I don't know how hard it would be to do this, but if you guys already have a script that you go through maybe you could just share that with us. But I'm guessing that some of it might be ad lib.
