The third and final GNOME 3 Test Day is coming up this Thursday, 2011-04-21. Now the final GNOME 3.0 release has been made, this event will focus on testing its integration into the upcoming Fedora 15 release and exposing any remaining bugs that can be fixed with minor updates. This is a great opportunity to test out the final GNOME 3.0 code on a late pre-release Fedora 15 base, and help the Fedora and GNOME teams to produce a great release. There will be live images available to make sure you can test easily and without the need for a permanent installation — there's no need to be a Fedora user to help out. There are comprehensive testing instructions on the Wiki page, and assistance from the Fedora QA and desktop teams in #fedora-test-day on Freenode IRC throughout the day (WebIRC link for those without an IRC client)."
