No problem! I like Mitsuo's blog too.
Yeah, the address for fanletters was T-Fenix, but I don't think he broke up with them, since there's a "T-Fenix Kazuki" who sometimes posts in his blog (that's the guy who warned people about making dumbass comments).
What exactly is T-Fenix, anyway? I assumed it meant "Taiji Fenix" and was his personal management group or something along those lines, but I don't really know for sure.
Oh yeah, I forgot I have Kenji's URL too:
http://dtr.way-nifty.com/Is it just me, or does his new year's photo look like a cross between Taiji and John Lennon?
