In this chapter, you've learned how to start using the core features of your new desktop. These concepts should allow you to perform most of the day-to-day tasks when using your computer and provide a base from which to explore the other applications installed on your system. This solid grounding in the desktop paves the way for you to meander through the rest of the book, learning about the more advanced uses of your new system and exploring the enormous flexibility that Ubuntu provides.
Always remember that there is a wealth of help and documentation available online. If you ever find yourself stuck, take a look at the Ubuntu Web site at www.ubuntu.com or the Ubuntu documentation at http://help.ubuntu.com and make use of the forums, wiki, mailing lists, and IRC channels. Much of this is easily found in links provided for you in System > About Ubuntu in your menu.
