For something like the JFBC Fan Module (also known as the Facebook Like Box), there's a few options:
* Many templates have a module position for under the component or article output. If yours has a position like that, configure the SCSocial Wdiget -> Facebook -> Like Box to appear in that spot
* Create a template override for your article view and add the {JFBCLikeBox ..} tag wherever you want it to display
I hope that helps, but if you have any other questions, just let us know.
Thanks,
Alex
