Um, jeharsy, relax. I didn't remark about anything. I asked a simple question. And I had no idea you were from another country, or that English was not your first language. I am not a mind reader. I just asked a question. In fact, I still don't know what an "expocicion" is. Is it what we call in the States a "thesis?" Are you writing a paper? Or are you trying to decide your "major?" Perhaps if you define it more clearly, people might be able to help you better. (Sheesh, people around here are so jumpy these days.) --jjsemp Oh, and when I'm rude (which I certainly can be at times) you'll know it.
