Mobiplex includes support for DNN social modules. The skin includes options for whether or not to display the social icons at the top of the skin. If you are building a site using the DNN social modules, you may want to include these icons.
However, if you are not using the DNN social modules, you can use a skin layout that does not include the social icons.
You also have the option of weather or not you would like to include the image slider in your layout.
