I was trying to setup a little social box for Google author rank that looked nice. Don't get me wrong the CSS was nice but the settings page just had me selection social network links for sharing and nothing to put my rel=author tag into without displaying twice. I had to use custom fields. Seriously this is garbage and until it is STRONGLY IMPROVED it shouldn't get more than 1-2 stars max.
Terribly written tutorial also, it confused me badly.
