Hello,
 
I was on this page
 
http://docs.fedoraproject.org/yum/en/sn-using-repositories.html
 
It said:
 
Fedora Extras Repositories for Previous Versions of Fedora Core

You must manually configure Fedora Core 3 systems to use Fedora Extras, using the instructions at http://fedora.redhat.com/projects/extras/.

The extras link didn't work.
