It’s not called “youtorrent”, and it never has been.
It’s all right there in the name – µtorrent, not utorrent.
That’s not a “u”, that’s a “micro” symbol. You can tell, because it doesn’t look like a “u”, due to it looking like a “micro” symbol.
It’s “microtorrent”. That’s the name of the software that you use, if you’re speaking the name or don’t have a character map program handy.
It’s kinda funny to me that rendering it as html, one has to spell it the way it’s clearly intended to be pronounced: µtorrent
Maybe I’m a snob and borderline grammar nazi. But this has always been a pet-peeve of mine, and I just want you to know that I judge your intelligence based both on you calling it “youtorrent” and especially on you not knowing what I’m talking about when I use the correct name.
