I'm Vex. I've been aware of Socionics for a bit, about 6 years or so. When I first took the test at sociotype.com, I distinctly remember scoring as an LSI/ISTj.
Not sure of MBTI since I've grown quite out of touch with that, and it all depends on the choice of theory anyways.
Anyways... thank you if you read this, and have a lovely day.
