A couple years back, I made a yahoo widget that would check JK Rowling’s official site for updates. I never really let it out of beta and eventually abandoned it out of lack of motivation. To my knowledge, it is not widely used, I would be surprised if one person knew about it! But anyway, i decided I might as well let out the source code for the thing in case anyone wants to improve on it! Anywho, all the code (including old versions) can be found at:
Feel free to use the code however you please, I am not going to go through the trouble of attaching a license to it. If you do happen to start using it, I would be interested in an email!
