Sorry for the late notice everyone, but today is Xfce Test Day in #fedora-test-day on Freenode IRC! The Test Day page
has further details and testing instructions. There's a shiny new Xfce version, 4.8, landing in Fedora 15, so come along and help test it. And remember, GNOME 3 refuseniks, Xfce is probably your best alternative.
