Some people limit others from viewing their profile, but is it possible just to view their postings just for navigation purposes? I mean, can it be changed?
I don't think so. I use google more than this site's search function. That is, you have to remember some words of a post which you are looking for, and stick them in Google along with that person's username and add sciforums. Anyways, who you trying to look up??? I won't tell anyone.
