Is there any reason why she's using Red Hat 7.2 instead of a current distribution? I'm not familiar with older distros, but she would probably be better off with something like SUSE, Fedora Core, Mandriva, or ubuntu (or kubuntu if she prefers KDE over Gnome). They're free and available for download from their respective websites. You can find more information at

The consumer level Red Hat distro has been discontinued. Instead there is Red Hat Enterprise (not free) for business use and Fedora Core, which is made by the same people. Fedora Core is for individual users, is free, contains the latest (though not necessarily stable) software, and is used as a testbed for programs and features to be implemented into Red Hat Enterprise.
