I've come out from under my rock after having lurked for a while.
I am not completely sure of my type yet but I'm certain that extraverted feeling is in there somewhere. I've taken several MBTI tests and have had strangely varying results, so I'm now focusing on cognitive functions in order to determine what my preferences are. I am fairly sure, however, that I am a type 4 enneagram. Looking forward to learning more about this brain stuff!
