Man, that's weird--he's been a member the entire time I've been here, and I don't remember ever seeing his username at all.  And it's not like he didn't make a lot of posts, either.  Maybe not a ton for someone who's been a member of bitcointalk for 10 years, but still.  I had to look at his post history, and it's clear why his name didn't ring a bell, because he posted a lot in the altcoin section.

I hate to see young people die, and looking at that picture of him he looks as though he's bursting with energy and enthusiasm.  So although I didn't know him, RIP Joerii.  It's obvious he touched a lot of peoples' lives, and my condolences to his family and friends.
