The look and feel of a website reflects the website's identity and content. Therefore, it is important for the Administrator to be able to know and distinguish the differences between a Joomla template and a JomSocial template. In order to have a complete "look and feel" for your site, you have to change both templates.
Let's clarify a few things first. By analogy, the Joomla Platform is an operating system and the JomSocial component is the application in Joomla. JomSocial is a Joomla component. In Joomla, there can only be one component displayed at a time.
Now, let's talk about the Joomla template. Joomla's templates can be found in Joomla's Backend (Extensions > Template Manager). You can change the Joomla template and it won't change the "look and feel" of the JomSocial component.
Position of the JomSocial Component in Joomla
So some of you might be wondering, "where is the position of the JomSocial component placed in Joomla?" To answer that question, please open templates\[template_name]\index.php found in your Joomla directory.
The line responsible for displaying JomSocial is:
<jdoc:include type="component" />
