The correct place to ask for help with Debian is the debian-user
mailing list at debian-user@lists.debian.org. If you know how to use
IRC (Internet Relay Chat), you can use the #debian channel on
irc.debian.org. You can find general GNU/Linux help on the
comp.os.linux.* USENET hierarchy. It is also possible to hire paid
consultants to provide guaranteed support services. The Debian
website[5] has more information on many of these resources.

Again, please _do not_ ask the authors of this book for help. We
probably don’t know the answer to your specific problem anyway; if
you mail debian-user, you will get higher-quality responses, and
more quickly.
Always be polite and make an effort to help yourself by reading the
documentation. Remember, Debian is a volunteer effort and people are
doing you a favor by giving their time to help you. Many of them
charge hundreds of dollars for the same services during the day.
