Oooh, I didn't know you had worked for Viz, no wonder you're bothered

But seriously, I do understand the problem of jokes "lost in translation". Viz (I don't know if they did FLCL) and other translators have done a good in job keeping it funny. There was a recent thing Viz did that really bugged me, but I can't remember it at the moment. Ah, it's a fine line. But they don't need to edit and censor.
I don't care much for English translated manga anymore but it sure is handy to instantly pull up another person's translation when I get stuck or confused.
I wouldn't mind paying for that.
