I am an ex-member of INTPC, and also used to be a member of NCen. I felt bored and decided to join up. I used to think that I was an INTP, but am now certain that I'm an INTjay. Can't help the Ni!
I've just graduated from uni, and am waiting for my postgrad applications to go through. In the mean time, I'm working as a lab research assistant and am usually bored.
