Migrants to IJ, 2007

Very cool, thanks for finding it and posting!

I'm a little confused by the format of that page, though. It's ticky boxes, and a save button, right? But I ticked boxes, pushed save and then it just reloaded the page with none of the boxes ticked. Is this supposed to happen, or is my computer acting funny? If that's what's happening for everyone - how can I see that my selections actually went through, and how could I unselect them if I chose to in the future?
