Anything that goes into Fedora needs "karma". Packages must first be built on a build system called Koji. They are then passed along to a system called Bodhi where they collect karma before being pushed to stable.
Bodhi may be found at:
https://admin.fedoraproject.org/updates/
First, log on to Bodhi using your FAS credentials (There is a login button at the upper left).
(Bodhi1)
In the box at the upper right, type in the name of the package you wish to test
(Bodhi2)
You will be presented with a screen showing several versions of the package. For example, if you typed fedora-release-notes, the screen would be similar to
(Bodhi3)
If you click on one of the packages, you will see the Bodhi details for that particular package
(Bodhi4)
Clicking on the package name brings you to the Koji screen for the package
(Bodhi5)
Clicking on the task name
(Bodhi6) leads you to another very similar screen that shows the descendant tasks. Clickong on the "buildArch" line of the descendant tasks leads you to yet another almost identical page.
This time, however, near the bottom of the page you will find links to the build logs, the source RPM, and most importantly, the noarch RPM (the one you actually want!)
