Hide Group audience/content visibility in node When displaying a node belonging to some OG, the group audience and the group content visibility is displayed at the end of the node just after the content of the node.

Is it possible to disable that ? 
I would avoid code editing if possible.
In the OG content type, you will see a field for group audience. You can simply hide it in the Manage Field tab. Or, you could use CSS. In both cases, you are not hacking the core code.
