I've been playing with Drupal for a bit, and have gotten used to the idea of Content and fields. I am now trying to use Drupal Commons 7 to up my game some and improve how my site looks. Im a bit stumped however on how I can edit the look of my Group page. Id like to add a big image at the top, before the group content. I think this is done using panelizer but Im not sure.
First is this right? Second, if so, where can I look for getting started tutorial type stuff that explains panelizer and how it works with the underlying field system? Do I have to add a field to content somewhere? If so, what and where?
