The book starts off with a short introduction about social networks and a list of compelling reasons why one wants to set up her own social network rather than using an existing social network like Facebook or MySpace. It all comes down to what your particular goals are. The first chapter looks into why Drupal is a good fit for building a community website. Its modular design, use of known technologies and ease of installation, as well as the ample availability of modules help in that respect, and also clearly marks where the book is going next. The other half of the first chapter explains in great detail what is needed during the installation of Drupal to have a working setup. If you are already experienced with setting up Drupal you can skim through this chapter to verify that you did not miss anything with earlier installations.

The second chapter prepares the reader for using Drupal specifically targeted for building a community website. To do this the author comes up with his own example (Dino Space) which is used throughout the book. And while the subject may be far-fetched and very different from what you plan to do, it serves its purpose well. Throughout this chapter the author explains many Drupal related concepts and terminology like Nodes, Content Types or Blocks and how to use these to your advantage when designing your site.

So while the first and second chapters explains and prepares the reader, chapter three helps with important decisions regarding user contributed content and all aspects related to it. User Roles, Comments, Polls, Forums and Blogs. One thing that surprised me was how it is possible to write blog entries from Microsoft Word using a standardized API. And while it is not applicable to me (as a Linux user) I can see some benefit for others within the targeted community. Another topic from the book that I had little experience with is collaborating on a Book within your community. I was always amazed by the annotated PHP manual in the past and this possibility reflects that effort a great deal. The chapter also includes attention to how to automatically generate feeds or include feeds from others, something that helps growing the community.

The next chapter goes into how users can maintain their profiles, how profiles can be extended and themed and how profiles can be shared between websites. It also looks into specific modules to help you eg. integrate OpenID or avatars from other websites. Chapter five explains how users can interact and how the User Relationships and User Activity modules allow users to promote their own content and actions on their site. Much like how Facebook becomes a time log of individual actions of our friends. It also looks at Guestbooks, Contact forms and Groups covering more than I was looking for myself.

One thing I recently had to look into myself was how to communicate with your users. Some users register and then loose touch so there is a clear need to regularly update them about what is happening and what new content is available and that's where chapter six explains how to set up Newsletters or connect your social network to online services like Google Groups.

Drupal is mostly respected for its modular design and Drupal's author often states "If it cannot be done from a module, then that's a design bug which needs to be fixed". That said, almost everything is possible from a module, which offers great flexibility to anyone deploying Drupal to customize it to its own needs. Chapter seven explains in some detail how to write your own Drupal modules from accessing the database, interacting with other services as well as making it installable and customizable. The example shows how to interact with Google Maps from a Drupal module. But also points to similar modules for connecting to Facebook.

Another important aspect of any website is its design, chapter eight shows how to install and configure additional themes, but also explains how to modify existing templates and tweak CSS files. It does not go into great detail though, but it sufficiently points out where to look and how to experiment.

The last two chapters are a bit dim, chapter nine explains how to secure your Drupal site from automated spam and lists a few maintenance tasks every admin should know about. Much like chapter nine, chapter ten does not go into a lot of detail about how to promote your website. It mostly lists important aspects and in some cases provides links to experienced websites.

All in all I was surprised by the many items this book covers, especially the chapters about writing modules and modifying themes is something most buyers will not expect in a Drupal book regarding Social Networking. And while I believe there are better books about those topics, in general this book is a good introduction to Drupal and a guide for those who are also interested in the more advanced parts of Drupal.

I was particularly interested in this book as I set up my own family website based on Drupal and I wanted to know what technologies I missed, and what additional modules I could use to make our own family website better. In that regard this book confirmed for a large part that what I did with Drupal was how it was supposed to be, but I did learn some new tricks and new modules I never investigated before. This knowledge undoubtedly will be useful for some future Drupal-based projects as well.
