I'd say ENFP, but considering how little I know you, you obviously should take that with a mountain of salt
* E - because of that ability you have to Just. Keep. Going. You never seem to get tired, especially of socialising. I know I can have my Extraverted moments, but I always end up getting "tired" and having to retreat. You don't seem to go through that. BUT of course, the Internet is possibly the worst medium through which to determine Introversion/Extraversion, so the biggest portion of the mountain of salt should go to that letter
* NF - because you just reek of NF

There are some NFs that sometimes give me an NT vibe, but you don't.
* P. Because not J. But I'm awfully biased on that one, seeing as I am an INFJ married to an ENFJ, so I may not have a "full" view of what being an NFJ can cover. However, if I may use our discussion on the "too much fluff" thread as an example, I must say that I was very surprised to have you ask me why it matters to me, if it doesn't affect me directly. For both me and my husband, it's a *given* that if there are people who are unhappy with a system, then the system must at the very least be re-examined. That's typical Fe at work. And apparently you didn't feel that way. Which prompts me now to consider whether you might be Ne/Fi rather than Ni/Fe, and er, well, yes, it fits, it fits very well, especially since I do remember thinking quite a few times that you were emitting vibes that awfully resembled Ne (like, er, right now for example

Posting a totally open thread asking people for their idea of what your type is, that's just SOOO Ne

)
So I'll go with ENFP. Covered in a mountain of salt. I really don't have any problem with you being an INFJ, if that's what you are. We have different flavours of INFJ on this forum, and you'd only be another one. No big deal at all. Quite interesting in fact. So please don't go thinking that I'm trying to "evict" you from my type or anything, OK

?
