Hello,
this Thursday is Fedora KDE 4.9 Test Day which is one of the most popular testing events among Fedora users and developers.
KDE 4.9 has many new features: http://www.kde.org/announcements/4.9/ Please join this test day and help us to hunt down KDE desktop bugs before Fedora 18 Beta release!
For informations how to attend this test day, look at the following page: https://fedoraproject.org/wiki/Test_Day:2012-11-15_KDE_4.9
Join IRC #fedora-test-day on FreeNode and ask QA or developers for help, if you get into trouble. We can try to find workarounds and help with debugging. Please report all bugs at http://bugzilla.redhat.com/ under appropriate component. You can also report other Fedora 18 bugs not related to this Test Day, ask QA, if you don't know against which component you should fill the report.
See you in Bugzilla!
Best Regards,
Martin Holec Desktop QE, Red Hat Brno
