For those who aren't aware, yuckie_chan's list is a list of basically every subbed Arashi video ever, to the point where, if it's not on the list, it probably doesn't exist. It is, in my opinion, the single most useful resource in English-speaking Arashi fandom. Looks like it's being maintained by several people now.
On the same subject, a reminder that I made this post of important fandom links a while ago, for those who haven't seen it. Of course, this is an even more comprehensive list. We Arashi fans have a lot of great resources out there. :D
