Fedora.us is not the Fedora Project's official "Fedora
Extras". It's
still the current semi-official/unofficial Fedora Extras until it has
merged with the Fedora Project. The
http://fedora.us has one or two
articles about that merger.
fedora.redhat.com also links fedora.us as
the currently suggested way to contribute Fedora Extras packages. That
will change when the Fedora Project announces "Fedora Extras"
officially.
I submited some packages to be approved for Fedora Extras, following
the process at
http://www.fedora.us/wiki/PackageSubmissionQAPolicy and
nothing happened until now. No response, no yes, no no.
