You sort of already have sponsor rights in RPM Fusion as you are a sponsor in fedora.

But we don't need lorenzodalrio to be sponsored since it's already sponsored in fedora.
As a consequence he's automatically added to the packager group in RPM Fusion.

More accurately, I've manually added him to the fas, as we don't have a sponsor concept in RPM Fusion's fas. yet.
