Not my own project, but one I've just signed up for. It's limited to the UK, though.
Thanks for sending this our way. i'm now on their lists too.
My journal arrived this week and is now posted on to the next on the list. Good project! On the surface, incredibly simple and straightforward, but I was the fourth person to add to this one and you can already see how it's going to end up an amazing collection of writing and images.
