After the fairly dry material about configuring the server and internet connection, we're going to look at a few practical examples of how you can alter the configuration of the WACS system to better reflect your needs, desires or even whims. We're going to look at how you would set about changing the colours, the page layouts and the menus. In all cases, you need to know where the wacs.cfg file for the site you wish to modify is, have write access to it and a suitable text or XML editor available to you. Our examples are going to show you the raw XML file, but in a speciallist custom XML editor you would merely expand the trees to reach the same attribute and alter it there.
