According to
http://fedoraproject.org/wiki/Documentation_Beats
there are quite a few open beats, unconfirmed writers (*), and beats
still containing F11 content (#).
If you have begun work on a F12 beat, it would be helpful if you could
confirm your status (remove *), and update the status of the beat if
there is no longer obsolete F11 info present (remove #).
If you've never written a beat, why don't you consider joining in on the
fun?! It's not as difficult as you may think, and you will learn a lot
about the topic you choose to cover.
