If you're not an ENFJ, I am certain that you are an INFJ. Sometimes, INFJs develop a very solid Fe, and can appear very much like ENFJs, especially in situations where we've learned that being our sweet, harmonious, INFJ selves isn't helping anyone.
I'm no exception.
Your test result scores look a lot like mine, just a little more ENFJ. That's why I guessed ENFJ. But, you don't have all of the ENFJ traits with respect to your online presence. Most importantly, I've found that ENFJs don't really spend much time pondering things, and certainly don't spend as much time poking around forums as we do. They live in the 'real world' more than we do, and as such don't seem to waste as much time on the internet, lost in their contemplations, or taking the time to express their thoughts with eloquent grammar. They're usually to busy to do something like this... which is why there are so few ENFJs here, and even fewer who post regularly.
