I can recommend just c/p and print the addresses in kana/kanji. As long as it says "JAPAN" in Arabic letters, the postal service's going to throw it in the right direction and it'll reach her.

I think we have so many lovely ideas that there will be things to do. We just need to collect them a bit and poke at them so they are beaten into shape before we go public.

Also, as for people reacting strongly: it's sort of the FW horde reaction again. Enraging and ranting just to do it. Of course Nitta-sensei has been naive and done something not so clever, but she didn't steal any stories or something like that.
