Well, I never took MBTI seriously till recently when I started reading about it. And then I was like, hell yeah it makes sense (kind of)! :P I am an INFJ and the purpose of this group would be to come together and do indoor/outdoor social activities(maybe playing games?), talk, music, books ... basically fun.
I am a Ph.D. student at EPF-Lausanne, but it does not mean this group is only meant for students!
