This is your home page. You have the option to have this text show up or not and the text on all the pages you create is infinitely editable by you. In fact, every page that you create in your ADMIINISTRATION AREA has the option for text to show up or just display a full background image.
By using Background images you can get really creative. Using a program such as Photoshop, you can add text directly onto your background images before you upload them in your ADMINISTRATION AREA.
Simply go to your ADMIN and select "Appearance and Text" and then select "Manage Page Text". From there you can change this text, change or add backgrounds, and add as many pages as you like.
