I would definitely say AvereX is an INFP- I get a strong Fi vibe from him.

I'm not sure about some of the others in terms of Introversion/Extraversion. (Jen: INFJ or ENFJ)
I get an ENFJ vibe from Jen but we must remember that people will seem more extraverted on internet forums- we are typing instead of talking and most of us are usually alone when on MBTI Central.

In terms of cognitive functions, it is possible for people to use both their main introverted and extraverted functions about equally.
