I saw that post some time ago. Simply hilarious. But I also feel just a little ashamed when I see it, because when I first registered, I nearly gave myself a Sephiroth-related name... but I thought the better of it. I've found that I prefer not sharing my username with 22 other people, though it is still a Final Fantasy reference.
Three Great Sephiroths... now that is just priceless. The Cult of Sephiroth is coming, people!
