how to uninstall KDE desktop in fedora 11

please i would like to uninstall the KDE desktop in my fedora 11,previously i was using the default gnome desktop,i want to revert to gnome desktop

You can still use gnome even if KDE is installed. Did you just want to change your default? Is there a reason, besides freeing up space, that you wanted to remove KDE?

I just want to free space and also change to gnome desktop
