  1. Hi Amit,

    I am writing to you for Packt Publishing, the publishers of computer related books.

    We are planning to publish a new book on jQuery UI titled, jQuery UI Theming- Beginner’s Guide. While trying to look out for some potential authors to write this book, I came across your site and saw the jQuery UI theme you have developed. This gives me an impression that you could be a potential author for this book.

    Targetted at web designers who want to create themable user interfaces, this book will teach creating themable applications with jQuery UI

    To give you an idea about the way things work at Packt:

    – The editorial team at Packt works with the author through out the project.
    – We pay a royalty of 15% and an advance against the same.
    – The marketing team at Packt ensures that the book is well promoted.
    – In its ongoing commitment to OpenSource, Packt donates a percentage of revenue generated by the book to the OpenSource project on which it is based. We have donated more than 100 000 dollars since inception in 2004.

    Could you please let me know if you find it interesting to author this book?

    Thanks
