TerranTribune has 3 module class suffixes which are structural in their purposes. They allow you to change the layout of the module itself. These are -title (this loads the title bar on the module) or -notitle (this removes the title bar on the module) or -ad (provides a layout suitable for sidebar ads).

To use these, just add the hilite names in the module class suffix parameter of the module in the Module Manager located in your Joomla administrator.
