I want to thank you for doing this. As an Arashi fan for ~6-7 years I took for granted how relatively easy it was to get their shows, clips, articles, etc subbed. When I "came back," if you will, to the fandom after 2 years I saw how strict and closed off the sub groups have gotten with most of being inactive. I completely understand and respect their decisions of course, but as a foreign fan who always wished Johnny's and even Japan in general to embrace the international markets like you see with South Korea, it nonetheless saddens me.
I'm always happy when I see Arashi stuff (nonsubbed) get mentioned (like on reddit.com/r/JapaneseGameShows) and wish I could share the Arashi goodness but the hurdles that they would have to go would be too much. My hope is that there would be a community for Arashi like the one for Downtown on reddit.com/r/GakiNoTsukai.
Sorry for the tangent =p I wish you luck and if you need help feel free to ask.
