Hallo! I registered on a similar forum as well, but in reading google searches on ISFJs, I found some threads here and felt there was no harm in joining another. Don't strike me down with your force or anything.
Anyhow; I may or may not be an INFJ (I certainly used to think so, but I've been testing so much lately that I've been handed more than one ISFJ and INTJ as well.) Identity crisis?! Seriously, the F/T swung from 60% on the F side to 1% on the T side to 60% on the T side... how does that happen unless I'm subconsciously trying to make desirable answers work in my head?
Anyhow, here I am. I'll probably be asking lots of questions and injecting my perspective in a lot of places as well.
