You can fix bugs for many packages, but you should only assign your self
to a package, if you want to take care for bug reports in a long term.
I suggest to make small fixes and pull requests first and get familiar
with repoman + git first.

That is a good start. There are many new informative links.
You can join us on IRC and tell us what you already can do, what your
interests are. We will have lists with things to do in all flavors and
difficulties. You may ping me on IRC, my nick is jstein.
