How to use this forum (and about "Visual Identification")
Say you want us to help you type your friend Tom. Post a thread about him here! In that thread, first and foremost you should tell us what Tom's personality is like, and respond to whatever questions forum members might ask you about Tom.
You are also encouraged to post pictures and/or videos of Tom, since there are often visual clues as to a person's type. This method is known as "Visual Identification." Videos are highly preferable, but if you choose to post pictures (and you certainly don't have to), I strongly recommend that you
1) post multiple pictures, if possible, and
2) post more than just pictures (i.e. description)
Personally, for visual identification I prefer to have dozens of pictures (or better, someone's whole facebook account), but this is a forum, and there are issues with privacy and space. If you follow these guidelines, the typings you get will be more accurate.
