I never left, c_b. I just decided that I would comment only if I had anything useful to say, and it turns out I rarely do.
I've never actually heard piurci used in speech--I've only seen it written down. The transliteration of Yupik is very tricky. I have a call in to a friend of mine on the correct pronunciation and I'll send it along when I get it. Many of my students use it when they communicate with my via their blogs or e-mail as a closing.
