A new section has been added to XulPlanet! It contains answers to some common XUL questions, and provides a number of new examples.
I'm hoping others might contribute additional examples.
By the way, we've moved to a new host, so if you see anything broken, let us know. I do want to thank the XML Workshop for hosting us for free all these years. But now that XulPlanet has gotten bigger, it's time to move on.
