There are several ways to contact me in case you have a question about the
book or the examples.
You can reach me on my blog http://www.wait-till-i.com which is my favourite way of contacting as you can check if your question has been answered already.
Please keep contact to a minimum and don't be too miffed if it takes me a while to answer or if the answer is less wordy than you'd like it to be. I am soon very busy with my real job and the follow-up to this book.
