Not only don't I see which OS but there are so many areas this could be in any number of OSes so let's see and read a bit more.

I went to my profile and filled in everything and it saved everything but the computer info. I tried three times. Am I supposed to enter it in a certain way, or are there certain symbols I am not allowed to use? Also it wouldn't allow me to even approach the 4000 letter maximum it claimed it would let you, it was more like 1600.
How do I enter this info? (BTW I'm sorry I didn't know where to put this question.)
