Am I going blind? am I blind all ready

I got the 8.1 professional version with two main books but I don't seem to find in the books, just a few page I feel all that is needed on were to install programs, for example would you use /opt or /usr if you use /usr would you put it in /usr/lib or /usr/local or would you put it somewhere else, Linux can be very frustrating to the beginner, I am making head way (I think) but still have a list of things I need to fix up. try http://homepages.paradise.net.nz/erichard/linux.html -- From Eric (KMail 1.4.3 in Linux, SuSE 8.1) http://www.oh-bugger.net.nz http://homepages.paradise.net.nz/erichard/ NO ATTACHMENT WAS SENT WITH THIS EMAIL IF THERE IS ONE IT IS A UNDETECTED VIRUS, IF THERE IS ONE PLEASE LET ME KNOW ....
