Re: what's your major?
I think the correction about using "the university" did not refer to your signature line, but to the part where you said "ask an exchange student from America his major at my university". I assume you meant that the American person is attending the same university as you. I suppose some people might say that "my university" sounds like you own the university. My personal feeling is that it sounded OK.
