Just to make you aware, the first book written for Elgg is now available to buy.
The Triffid book (as we’re unofficially calling it) covers the 0.x codebase, and serves as a good introduction into installing and running your own installation.
If you are looking to create your social networking site by tomorrow, then this book is for you. You will be equipped with a social networking site even before you are through this book. You don’t have to be a hard-core programmer to do this. All you need is a computer with an internet connection and this book.
Next: Elgg the Movie (just kidding).
Update: the latest book is for Elgg 1.8, you can buy it here (Full disclosure: As an Amazon Associate I earn from qualifying purchases):
