The Fedora community can really use people who are willing to go through bugzilla and tame things down there. There are just a ton of bugs that the package maintainers will have no time to get to.
It's not the most exciting task, but it's something that almost anyone can help with in as small or large quantities as desired.
Also needed are community leaders for each of the architectures. E.g. Justin Forbes is The Man for AMD64, but we can always use peeps for ia64 and s390* :)
