I just wanted to welcome everyone to the forum for Professional Ajax. If you have any questions or concerns about the book, whether you think something is incorrect or you just can't figure out an example, post your messages here.
Please make sure your questions relate directly to the book, as there are other, more appropriate forums for general issues.
