Hi, Seth (who is unfortunately dead), still owns 3 packages: https://admin.fedoraproject.org/pkgdb/users/packages/skvidal?acls=owner
planet -- Flexible RDF/RSS/Atom feed aggregator
pyliblzma -- Python bindings for lzma
yum-utils -- Utilities based around the yum package manager
Whoever is interested in those packages should short circuit "Unresponsive maintainer policy": http://fedoraproject.org/wiki/Policy_for_nonresponsive_package_maintainers to items 6 and 7 and apply for those packages.
