One reason that Fedora Core can be a bit difficult to new users is the number of things that must be set up after installation. There's Java, Flash, getting 3D running right, mp3's and a host of other items that you might want. Sure, you can read through the 'how-to's' and configure things yourself... OR... there's Fedora Frog, a nice tool that's been around since FC-4 to help configure things for you. http://easylinux.info/wiki/Fedora_frog
Well, we'd like to see this important tool available for FC-6 and beyond, but the developer is under some time constraints and needs help. If you'd like to participate, please go to the site and contact him as described under "Help Needed".
