Tal, I always suspected that you had left out an "i."
But, I thought it referred to Frank Lloyd Wright's home and architecture school, Taliesin.
My name is a reference to the old book Listening to the Great Teacher that my parents studied with me when I was a kid. Not sure everyone here is old enough to remember it. Also, I am a teacher, so...
I had to add the extra r when I joined this site (I was GreatTeacher on the old JWSF) because GreatTeacher was already taken, though I've never seen hid nor hair of him or her.
But, I kind of regret it. If you don't know that book from the '60s /70s, then it sounds like I'm bragging. I'm a perfectly adequate teacher, but I wouldn't call myself "great."
