I love the new design and I'm eager to brandish a Stack Exchange t-shirt at Dreamforce, where do I signup for the goods?
There are several sites on the web, where you can create/design your own shirts.
Only problem, is that you need to have the rights to use the design.
I don't think we have these rights.
I did play with one (made an iphone 5 case :-) )
Another site is www.zazzle.com
If we can use the images, that will be awsome.
