Jeff Starr recently announced an extensive update for his popular WordPress book Digging Into WordPress. The book has been updated with a complete guide to using WordPress 3.1 and has additional updates and material throughout the book.
Unfortunately, the beautiful spiral bound paper version of the book is not available at present however you can download the PDF version of this awesome book instantly for only $27. This weekend you can reduce this price to $22 with the $5 discount code EarlyBird2011. With over 400 colourful pages of tutorials and walk throughs on WordPress and unlimited updates for free for life, Digging Into WordPress is arguably the best WordPress tutorial book available today. I recommend downloading the PDF sample to get an idea of the quality of the book.
