This is particularly for the newer members, but I guess everyone really:
Don't try to help type someone unless you're confident that you know what you're doing. I won't point the finger, but all the time I see people who have just gotten here poking around in people's "What's My Type" threads and just throwing things out there. 90% of the people on these forums still have a non-practicable understanding of the functions, and while it may sound arrogant of me to say so, it is the truth, and if people who are unsure of their understandings are playing around and throwing around illegitimate correlations or typings, they're going to confuse both themselves and those trying to type/be typed.
So please, unless you really know what you're doing, at least make it obvious that you're just "throwing it out there."
