Hi,
I just tested, and it still works the integration with Zazzle. To view the design on a T-shirt do this:
1. Press the “Product” button on the Tools panel. The Product panel will be displayed.
2. On the Product panel, press “Buy”. Then your design will be exported and a window will open at Zazzle.com showing your design on all kinds of merchandize, including t-shirts.
If you are a Pro user, the Sell button will be visible. then you can login to Zazzle, then on the Product panel, press “Sell”. Your design will be avialable to be used inside the Zazzle designer.
So the integration still works… It shows your design on all products at Zazzle and you have to select the merchandize you want.
