It's very easy. Under the user setting there is a box wherein you can put a new personality type. Since people often look at that box and assume that that is your type you can continue acting like how you always do... but your actions will be viewed through a new lens in the eyes of the forum.
Come, take flight with us my INTP fwend.... Let go the burden of Ti and let your wings stretch to their full crazy potential.
And you will royally screw people up ...LOL Makes good when people try to knock you based on "personality" also.
Take what I say with a grain of salt, because that's all it is compared to the ocean of complexity when it comes to actions and real life.
