The first time I "met" sensei in the chatterbox, he was helping someone out. He helped me out too, when I was just beginning.
I miss his calm voice, always patient with the newbies, and always helpful. He rarely seemed to get annoyed with noders who were driving everyone else up the wall (though maybe he'll read this and say, I really came off like that? What is this girl smoking?).
I don't know why, but just seeing his name at the top of the Other Noders list was somehow comforting to me as a newbie. I felt like there was someone I could ask questions to, and not get laughed at.
/me misses sensei too.
